Swage Locked Grating
Swage locked grating, mainly made of aluminum or stainless steel bars, is formed by inserting cross bars into pre-punched bearing bars and locking them under hydraulic pressure. It comes in three bearing bar types: rectangular, T, and I bars, with I bars being lighter and more affordable.


Pickling
High-grade steel grating is typically pickled afterproduction to remove scale and discoloration caused bywelding, which can lead to corrosion. During the picklingprocess, the grating is submerged in a bath that cleansesthe surface, leaving it metallically pure and corrosion-resistant.
Hot dip galvanizing
Hot-dipped galvanized steel grating involves submergingthe steel grating in molten zinc, a process calledgalvanization. This forms a strong metallurgical bondbetween the zinc and the steel, resulting in a durable.corrosion-resistant protective layer.
Powder coating
Powder coating is a cost-effective, durable way to colorgrating. The process includes degreasing, pickling, zinc.phosphating, and electrostatic powder application, thenbaking at 180'C. For enhanced corrosion protection, thiscoating combines hot-dip galvanizing with powder coatingAvailable in all RAL colors, with different gloss levels andtextures.
