FAQs on ideal painting process for steel fabrications

Selecting the most ideal painting system for structural steel fabrications and galvanised steel fabrication is a daunting task for Maintenance Managers and Chief Engineers. It becomes more critical when the steel fabrications and the machinery or equipment have to be installed in the most stringent working atmospheres such as coastal areas, highly humid area, nearly salty and saline atmosphere, areas with steam, water vapour, and chemical fumes, places with high operating temperature. Pradeep Vaidya, CEO of Innovative Coating Industries explains answers to the FAQs that help in obtaining the best results from a painting system, in terms of long equipment life, highest anti-corrosion and aesthetics.

Frequently Asked Questions (FAQs)
For which types of steel fabrications and the industrial sectors, this painting process is recommended?
We recommend this for painting and re-painting of MS and GI structures, fabrications, PEBs, metal buildings, off-shore platforms construction, all rusted and non-rusted steel fabrications like solar power plants, HVAC plants, ready mix plants factory trusses, support structures, tank farms, chimneys, steam, water, chemicals and petro-solvents pipe-lines, columns, I-beams, bridges, dams, transmission towers, telecom signal towers, EOT cranes, formworks and scaffoldings A/c ducts.

Which are the products should be selected?
Products must be safe for workmen, low fuming, non-toxic, and readily available. These products must have min 12 months of shelf-life and the metal cleaners shall be water based (non-flammable). Premium grade anti-corrosion products will prove quite useful.

What is the process sequence to be followed?
The exact sequence to be followed is pre-cleaning, de-rusting (surface rust removal), and painting.
Pre-cleaning: Complete removal of oil and grease, surface rust must be ensured. This can be carried out by chemical cleaning, solvent cleaning, sand blasting, sand papering, grinding, mechanical cleaning or any other means.

De-rusting: The chemical de-rusting is easily accomplished by use of RUSTOGEL 1406 offered by Innovative for all corroded mild steel fabrications and structural steel. These cleaners are based on phosphoric acid, solvent, wetting agents and foaming agents.

Painting: Innovative’s recommended products are Zinkote 20 GP and Zinkote 20 Premium. Zinkote GP is manufactured using 99 per cent pure zinc dust rich paint and Zinkote 20 Premium is manufactured using 99 per cent pure zinc flakes rich paint for highest corrosion resistance.

Is zinc rich paint (for cold galvanising) available in ready-to-use aerosol spray format for on-site use?
Yes. Zinc rich paint is also offered as Zinc Metal Spray (light grey finish) and Zinc Bright Spray (silver bright finish) in 500 ml self spray aerosol spray cans.

What are the advantages of using aerosol sprays?
Zinc Metal Spray (light grey finish) and Zinc Bright Spray (silver bright finish) offered in 500 ml self spray aerosol spray cans are most convenient for on-site use, offer very uniform zinc coating film.
