Heavy Duty Serrated Welded Bar Grating for Industrial Walkways and Platforms

Welded bar grating

Welded bar grating is also called metal open bar grating. Welded bar grating, also known as metal open bar grating, comes in two types: smooth and serrated. Smooth, or plain steel bar grating, is more popular, but serrated grating offers better skid resistance.

Press Lock Grating

Made from low carbon steel, stainless steel, or aluminum, is created by bonding slotted bars under hydraulic pressure. It's strong, durable, and widely used in industrial and commercial applications like stair treads, platforms, walkways, and covers. Serrated surfaces enhance anti-slip properties.

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.
