Surface Treatments

Shot-blasting prepares raw steel profiles and plates by thoroughly cleaning their surfaces before cutting and fabrication. Materials are shot-blasted in-house through our brand-new Voortman VSB-1500-4 which automatically delivers an optimally finished surface to SA2.5 standard and compliant with BS 7079. Blasting grit is removed after shot-blasting by a brush automatically positioned to the correct height above the material.

After fabrication, steelwork is painted in our dedicated paint shop to BS 5493 and Engineer’s specification, using industry-leading coatings to deliver a cost and time-effective finish. Thickness is regularly tested to our ISO 9001 procedures. Our paint application process undergoes continuous review by the paint manufacturer to ensure consistent quality.

Most steelwork is painted in grey or white, using Sherwin Williams Macropoxy C400V3 Zinc Phosphate Primer/Buildcoat applied between 75 & 250 microns per coat. We may accommodate other specifications and colours upon request.

For enhanced durability and external applications, we offer hot-dip galvanising to BS ISO 1461 standards, with coating thicknesses of 85 or 140 microns.

We also arrange off-site intumescent fire protection coatings compliant with SCI P160, with on-site painting of connections and installation/transit damage carried out by approved contractors.
