Rust and corrosion are among the most damaging — and most expensive — issues facing industrial and commercial structures. Left unprotected, steel deteriorates silently, day after day, until a small problem becomes a major repair and a repair becomes a replacement. Corrosion protection flips that logic: it defends the metal before the damage ever starts. Sicon Group protects industrial and commercial structures across South Africa from the slow, costly march of corrosion.

Why Corrosion Is So Costly

Corrosion is relentless. As long as bare steel is exposed to moisture and oxygen, it keeps working — and it doesn't only attack roofs. It eats into cladding, structural steelwork, gutters, tanks, silos and pipework alike. Globally, corrosion costs industry an enormous amount every year, and every uncontrolled instance of it on your site is a small piece of that bill.

For a single facility, the consequences stack up fast: perforated roof sheeting and leaks, weakened structural steel, failing equipment, safety and compliance risk, and — eventually — the expense and disruption of replacing what could have been protected. The real cost of corrosion is never just the rust you can see.

Protection Beats Cure, Every Time

There are two ways to deal with corrosion: treat it once it's taken hold, or protect the steel so it never does. The second is always the cheaper path:

01

Protecting Costs Less

Applying a protective system to sound steel is a fraction of the cost of cutting out, treating and replacing steel that's already corroded.

02

It Prevents the Damage

Protection stops the perforation, the leaks and the structural weakening before they ever happen — so you're not paying to repair the consequences too.

03

It Extends Asset Life

Well-protected steel lasts for decades. Unprotected steel in a harsh climate can be failing within just a few years.

How We Protect Steel from Corrosion

Effective corrosion protection is a system, not a single coat of paint. It comes down to:

  • Proper surface preparation — cleaning back to sound steel, because protection only bonds to a properly prepared surface
  • The right primer — including zinc-rich, sacrificial primers that protect the steel even if the top coat is scratched
  • Barrier coatings — sealing the steel from the moisture and oxygen that drive corrosion
  • Attention to the weak points — edges, welds, joints and fixings, where corrosion almost always starts
  • A specification matched to the environment — coastal, industrial and high-UV sites each need different protection

What We Protect

Corrosion protection isn't limited to the roof. Across an industrial or commercial site, we protect:

  • Roof sheeting and side cladding
  • Structural steelwork and frames
  • Gutters, downpipes and drainage
  • Tanks, silos and vessels
  • Pipework and ducting
  • Walkways, handrails and access structures

Protection Is a Programme, Not a One-Off

Corrosion never sleeps, so protection can't be a once-and-forget job. The most effective approach is a managed programme: apply the right protective system, then inspect it regularly, maintain the coating before it fails, and re-treat the vulnerable points before corrosion can get a foothold. Managed properly, a protected structure stays protected for decades — which is exactly the return a corrosion-protection programme is designed to deliver.

Defend, Don't Repair

"Every rand spent protecting sound steel saves several spent cutting out and replacing corroded steel later. Corrosion protection isn't a cost — it's insurance on some of the most valuable, hardest-to-replace assets your business owns."
