Repairs to Steelwork

Steelwork requires regular inspections to determine the degree of deterioration of existing coatings. They are treated according to the rating given.

Areas of high traffic, high wear, or in the case for protective coatings, high moisture, surface contamination or physical damage may require more regular inspection.

Areas for particular attention are angles, bolted connections including bolt holes, weld seams, stitch welding, sharp steel edges channels, web members of trusses, backs of double angles, stiffeners, gussets, gap joints or embedded steel in concrete and other areas where the coating may have been perforated or damaged by other trades.

All traces of rust must be removed via mechanical means then spot primed and top coated. This should be carried out by a suitably qualified professional applicator.

Steelwork Ratings

Category One and Two:

No film damage other than dirt and minor staining, soiled, stained, ingrained dirt, chalking or loss of gloss. Areas nominated as category (1) or (2) above should be swept, dusted or vacuumed to maintain optimum appearance. (Floor and eye level horizontal surfaces should be treated daily). Use a soft cloth or soft-bristled brushes where possible. Test mechanical methods to ensure they do not damage the finish.

Category Three:

Minor film damage (cracking, flaking or erosion of topcoats) in small areas. Areas rated as category (3) soiled/stained/ingrained dirt should be washed with mild detergent solution using soft cloth or bristled brushes and thoroughly rinse clean with water and allow to dry.

Category Four:

Minor corrosion where up to 0.5% of the base metal is showing signs of rusting. Rust staining should be treated as detailed for category (5) damage. All evidence of rust staining must be paid attention to quickly. Rust staining is a demonstration of concerns in a nearby area that should be addressed.

Category Five:

Major damage (corrosion over large areas) or excessive rusting. Rust staining should be treated as detailed for category (5) damage. All evidence of rust staining must be paid attention to quickly. Rust staining is a demonstration of concerns in a nearby area that should be addressed.
