Frequently Asked Questions
Mill Finish is the natural steel state and will corrode within days if not treated. Galvanized grating is dipped in zinc, providing a glossy finish and superior protection against rust and corrosion.
Depending on the environment, galvanized steel gratings are designed to last more than 30 years, even when exposed to highly corrosive industrial settings.
Yes, our steel gratings are highly adaptable and can be custom fabricated to fit any structure, shape, or size according to your technical drawings.
Serrated Galvanized grating is recommended for high-slip environments as it provides extra grip and traction for safer walking surfaces.
Common applications include industrial flooring, walkways, bridge decks, trenches, steel mills, warehouses, chemical plants, water treatment facilities, and oil refineries.
Powder coating offers the best aesthetic flexibility with a wide variety of colors and a very efficient paint finish, whereas galvanizing is superior for raw corrosion resistance in extreme environments.
