In Focus – Cut Edge Corrosion

Corrosion is a persistent challenge many industries, infrastructure, and everyday objects face. However, cut edge corrosion is a less well-known form of corrosion, which often occurs in metal structures and can lead to significant damage if left untreated.

This blog explores the causes, prevention strategies, and treatment methods for cut edge corrosion in industrial and commercial roofing systems.

What Is Cut Edge Corrosion?

Cut edge corrosion, also known as edge peel corrosion, occurs along the cut edges of coated metal sheets or panels, typically used in construction, cladding, or industrial settings. This phenomenon primarily affects materials such as steel and can compromise the structural integrity and aesthetics of a building or structure over time.

Causes of Cut Edge Corrosion

Cut edge corrosion is chiefly caused by the exposure of raw metal edges that were originally coated for protection. Several factors contribute to this type of corrosion:

  • Weathering: exposed edges of metal sheet panels are highly susceptible to the elements, including rain, wind, snow, and ultraviolet (UV) radiation. Over time, the variable weather conditions can break down the protective coating, leaving the metal vulnerable to corrosion.
  • Incorrect installation: inadequate sealing or installation methods can leave gaps, overlaps, or exposed edges in metal sheet cladding. These gaps provide entry points for moisture and oxygen, accelerating corrosion.
  • Coating degradation: coatings on metal surfaces degrade naturally over time, especially in harsh environments in coastal or exposed locations. When this happens, it leaves the underlying metal exposed and vulnerable to corrosion.

Prevention of Cut Edge Corrosion

Preventing cut edge corrosion is critical to extending the lifespan of an industrial or commercial roofing system and the structure it sits on. It can also minimise expensive repair costs – here are some preventive measures:

  • Quality coatings: start with high-quality protective coatings designed to withstand the specific environmental conditions of the site. Regular roofing inspections and appropriate maintenance can help ensure that coatings remain effective.
  • Correct installation: employ experienced professionals, such as Retain Limited, to install metal sheet panels and ensure that all cut edges are sealed correctly to prevent the ingress of moisture.
  • Design considerations: when designing structures, consider using coatings with extended longevity. This can help reduce the frequency of any repair and maintenance work.
  • Regular inspection and maintenance: conduct routine inspections to identify early signs of cut edge corrosion. Address any issues promptly to prevent further damage. At Retain Limited, we are proud to offer repair and maintenance services and a drone roof inspection service.

Treatment of Cut Edge Corrosion

If cut edge corrosion is identified, it’s essential to take immediate action to prevent further deterioration of the roofing system. A professional roofing contractor, such as Retain Roofing, can take the following steps:

  • Clean the affected area: remove any loose rust and coating materials from the affected area using appropriate tools and techniques.
  • Surface preparation: prepare the surface by abrasive methods, such as sanding or abrasive blasting, to create a clean, rust-free surface. This will allow for proper adhesion of a new coating.
  • Repainting: apply a high-quality, corrosion-resistant coating to the cleaned and prepared surface. Choose a coating suitable for the specific environment to provide long-lasting protection.
  • Regular maintenance: implement a schedule to inspect and touch up coated edges as needed to prevent future cut edge corrosion.

Our Conclusion

Cut edge corrosion is a common problem in metal sheet roofing systems, but it can be managed with suitable preventive measures and prompt treatment. By understanding the causes, prevention strategies, and treatment methods for cut edge corrosion, we can ensure our industrial and commercial roofing systems offer longevity and structural integrity.

Regular inspections, quality coatings, and correct installation practices are all crucial factors in combating this form of corrosion and preserving the life of metal sheet roofing systems.

World Mental Health Day

Today is World Mental Health Day. It is a time when we reflect on the importance of mental well-being and how we can collectively contribute to a mentally healthier world.

A primary objective of World Mental Health Day is to undo the lingering stigma surrounding mental health. Even though mental health conditions impact millions of us globally, many are still reluctant to seek assistance due to fears of being judged or discriminated against.

This annual event actively promotes an open dialogue about the subject of mental health, conveying that seeking help is acceptable and actually a sign of strength. Please be assured that it’s perfectly normal not to feel ok sometimes.

Think about how you can make a difference today and in the future. It could be as simple as checking in with a friend or family member, sharing resources, or attending a local mental health event. Even the smallest actions can create a ripple effect, contributing to a world where mental health is prioritised, and stigma becomes a thing of the past.

If you or someone you know is struggling with their mental health, there are places you can go to get help. Click here to learn what support is available, and please do remember that you are not alone – help is out there.

Devon & Plymouth Chamber Welcomes Retain Limited as Key Patron

The Directors of Retain Limited are thrilled to reveal that the company has become a Patron of the Devon & Plymouth Chamber of Commerce. Livewell Southwest joins us after accepting patronage at a hugely exciting time for the Chamber.

This winter marks the 210th anniversary of the Chamber – two centuries of proudly supporting the region’s businesses. So much of that longevity and success is thanks to the patrons of the Chamber, who represent some of the best-known and respected names in the local business community.

Jamie Gibbs, Retain’s Founder and Director, commented: “The Retain Limited team and I are very excited to become a Patron of the Devon & Plymouth Chamber of Commerce.

“This patronage presents a unique opportunity for us to grow our local and regional visibility and become further connected throughout the southwest of the country.

“The patronage also offers us many opportunities to support the Devon and Plymouth business community with our unique and award-winning three-in-one services within the construction and renewable energy sectors.”

The Devon & Plymouth Chamber is delighted that two of their most well-respected members and collaborators have stepped up to become Patrons. Chamber Chief Executive Stuart Elford said: “We’re absolutely thrilled to welcome not one, but two new Patrons to our Chamber family.

“Retain Limited and Livewell Southwest are both hugely successful and influential organisations here in the southwest.

“Through their support for the Chamber, our patrons demonstrate their commitment to the development of the economy and business throughout Devon and Plymouth.

“Our patrons will take centre stage as we look ahead to our packed events programme for the rest of 2023 and beyond. And we’re also counting down to this year’s Devon Business Show, which promises to be a true celebration of our region’s thriving business community.

“Our Patrons play a unique role in developing the future of our region, and the Chamber is far stronger with the support and Patronage of Retain Limited and Livewell Southwest.”

Patrons of the Chamber are some of the best-known and respected names in the business community. They are woven into the Chamber’s extensive lobbying activities and become one of the region’s principal voices.

Revving up the Fun!

In our latest team-building event, the Retain Limited team enjoyed a thrilling few hours at Plymouth Karting on a Friday afternoon. As you can imagine, the competition was very fierce, and we’ve just about recovered from our whiplash injuries! 

We had three sessions altogether, which culminated in a 20-lap final race. Our times were calculated throughout a qualifying session, and we lined up on the grid in true grand prix fashion. The adrenaline was well and truly pumping in everyone as we waited for the green lights. 

After a dramatic and incident-packed final 20 laps, our Technical Director, Darren Notman, was first across the line and through the chequered flag. Daz was followed by second-placed Sam Betts (Quantity Surveyor), and James Styles MCMI (Operations Manager) finished third. However, some of James’s tactics were questionable, to say the least! 

Ultimately, it wasn’t about who won or lost the race (although Daz would disagree!). It was about the team’s realisation that sometimes it’s good to shift gears, take a break from the spreadsheets, and be let loose in a go-kart!

Many thanks to everyone at Plymouth Karting for your hospitality – we all had a blast.

Work-Related Fatalities on the Rise

A recent Health and Safety Executive (HSE) publication reports that 135 workers in Great Britain were killed in work-related accidents in 2022/23. This was an increase of 12 fatalities (10%) from the previous year.

Also, 68 members of the public sustained fatal injuries from work-related accidents. This is a 20% decrease from the 88 deaths in 2021/22, significantly lower than the number of fatalities recorded before the COVID-19 pandemic hit our shores.

The number of fatal injuries in the workplace fluctuates year-on-year. Over the last ten years, the highest number has been 150 in 2012/13, and the lowest was 113 in 2019/2020. Whilst these numbers continue to vary, one thing remains consistent – the construction industry is the most significant contributor of fatalities each year.

The profile of fatal injuries to workers by industry sector in 2022/23 is generally similar to the profile of the last five years, with 82% of deaths in 2022/23 occurring in five industry sectors. These are:

  • Construction (45 fatalities)
  • Agriculture, forestry and fishing (21 fatalities)
  • Manufacturing (15 fatalities)
  • Transportation and storage (15 fatalities)
  • Wholesale, retail, motor vehicle repair; accommodation and food services (15 fatalities)

The 45 fatal injuries in the construction industry during 2022/23 was an increase of 16 from the previous year’s total of 29. However, this difference is not statistically significant, as the five-year average for fatalities in this sector is 37.

However, when you look at the fatal injury statistics regarding the number of fatalities per 100,000 workers employed, the agriculture, forestry and fishing sector comes out as the worst.

Falls from height, being struck by a moving vehicle and being struck by a moving (including flying or falling) object continue as the three leading causes of fatal injury. They have accounted for over half of all fatal injuries yearly since at least 2001/02.

In 2022/23, a total of 40 fatal injuries were due to falls from height, which accounts for 30% of all worker deaths over the year. This represents an increase of five fatalities from the previous year.

As a professional three-in-one contractor in the construction and renewable energy sectors, all our projects are above ground level, working on industrial or commercial roofs or from scaffolding. The health and safety of our workforce are constantly at the forefront of our minds.

We are proud to have developed market-leading health and safety policies that go above and beyond the standards of the sectors we operate in. These award-winning policies have been the solid foundations on which we have successfully built our business.

We’ve been annual winners of the National Federation of Roofing Contractors (NFRC) Gold Award for Health and Safety since 2016. These awards fully endorse our primary objective – the continued safety of our employees.

Jamie Gibbs, Founder and Director of Retain Limited, commented: “Compared to other countries worldwide, Great Britain is regarded as one of the safest places to work.

“However, the subject of health and safety needs to be a top priority for all organisations regardless of the industry they operate in. We must ensure our workers return home to their families after a hard day’s work.”

ERS Gold Status Achieved

The Directors of award-winning Retain Limited are thrilled to announce that they achieved the prestigious Defence Employer Recognition Scheme (ERS) Gold Award. This accolade follows the ERS silver and bronze awards which were attained last year.

Achieving the Gold Award reflects our continued commitment to supporting the armed forces community in a manner that aligns with the values of the Armed Forces Covenant.

Through a three-tier approach of bronze, silver and gold, the ERS scheme acknowledges employers’ different levels of commitment. It allows the Ministry of Defence to publicly thank and reward organisations for their support.

Retain Limited is privileged to have worked closely with the Royal Marines Charity (RMA) over the last few years. The RMA is a fantastic charitable organisation that provides lifetime support to the Royal Marines Family by any means required. We are delighted to offer our support, including mentoring and career opportunities for former service personnel.

With many of our employees previously serving in the Royal Marines, including Founder and Director Jamie Gibbs and Technical Director Darren Notman, we endeavour to offer employment opportunities to help former Royal Marines and other armed forces personnel adjust to their new lives as British civilians.

Retain Limited also strives to help educate, train and create bespoke career pathways tailored to individual skill sets to enable and encourage a successful and fulfilling life post-service.

In response to receiving the ERS Gold Award, Jamie Gibbs said: “We are truly honoured to have gained ERS Gold Award status.

“This is such a proud moment for everyone associated with Retain as we receive recognition for the endeavours we employ as a business to support the armed forces and veterans community.

“To have received all three ERS awards within 18 months is a wonderful achievement and must be applauded.

“Our new gold status further demonstrates to our staff and clients that we fully support the armed forces community and are a safe and trusted employer.”

The colour gold is familiar at Retain as we have been year-on-year winners of the National Federation of Roofing Contractors (NFRC) Gold Award since 2016 for our ongoing commitment to health and safety.

Furthermore, we have recently announced our support for Plymouth Argyle Football Club by agreeing to be a principal sponsor for the next three seasons. A gold-coloured Retain logo appears on the Argyle playing shorts, reaffirming our gold standard in everything we do as a trusted three-in-one contractor operating in the construction and renewable energy sectors.

Retain is Going for Gold with the Green Army

Plymouth Argyle FC has launched their new kit for the 2023/24 season today, and we’re thrilled to see the Retain Limited logo on the back of their playing shorts. We announced that we had become a principal sponsor of Argyle back in April, and today is the day we have all been waiting for.

Those of you who are familiar with the Retain branding will notice that the logo on the shorts looks a bit different. The Retain logo is in gold, perfectly aligning with our gold approach and the gold standard in everything we do as a three-in-one contractor in the construction and renewable energy industries.

The colour gold is well acquainted at Retain as we have been year-on-year winners of the National Federation of Roofing Contractors (NFRC) Gold Award since 2016. This accolade reaffirms our ongoing commitment to providing first-class health and safety procedures throughout the Retain Limited group of companies.

Furthermore, we have recently applied for the Defence Employer Recognition Scheme (ERS) Gold Award, which encourages employers to support defence and inspire others to do the same. We were awarded the ERS Silver Award in October 2022 and are proud to be an active Armed Forces Covenant member.

Jamie Gibbs, Founder and Director of Retain Limited, said: “The new playing kit looks fantastic, and we’re delighted to support Plymouth Argyle for the next three seasons as a principal sponsor.

“I have watched the club go from strength to strength over the last few years, and to see Argyle back in the Sky Bet Championship, with the Retain logo on their shorts, is a wonderful feeling for my team and I.

“I would like to take the opportunity to wish Steven Schumacher and his team all the best for the new season ahead of their first friendly tomorrow night against Hearts in Spain.”
