Customer Reviews

Yes we have received the reinforcing mesh and we are pretty happy with the quality. Many thanks! Chris

—— Chris Johnson

I have been ordering powder coated T 316 fly screen mesh from Qijie; unlike others, they never cut orders and always supply quality material to me.

—— Michael Jr. Venida

I had very bad purchasing experience with the previous supplier, for they always postpone shipment time. To my excitement, Qijie is always punctual.

—— Susan Miller

Your product good

Galvanized Steel Grating

Galvanized steel grating refers specifically to steel grating that has undergone heat-dip galvanizing treatment. It is made from high-quality carbon steel (such as Q235B) as the base material. After being welded or pressed and locked into shape, it is immersed in a high-temperature zinc solution, allowing the surface of the steel grating to firmly adhere to a layer of zinc-iron alloy. This galvanized layer provides excellent long-term anti-corrosion and rust prevention capabilities, enabling the product to have a maintenance-free service life of up to 20-30 years in outdoor and humid industrial environments. It is the most cost-effective solution for anti-corrosion steel grating.

Core manufacturing process: "Substrate molding + Hot-dip galvanizing"

The production of galvanized steel grating involves two core steps:
Step 1: Manufacturing of steel grid plate base board
1. Resistance welding forming (main process): The load-bearing flat steel and the crossbar (twisted square steel) are welded together as a whole using a large resistance welding machine. This process is highly efficient and has high strength.
2. Locking press forming: It is connected through mechanical methods of punching and locking compression, without welding points, and the shape is smooth.
Step 2: Hot-dip Galvanizing Treatment (Key to Corrosion Prevention)
This is the core process that gives the steel grating board its lasting vitality. The procedure is meticulous:
· Acid pickling and rust removal: Immerse the welded steel grating plates in a hydrochloric acid tank to thoroughly remove the oxide scale and rust from the surface.
· Water washing for plating assistance: After cleaning with the acid solution, immerse it in a zinc ammonium chloride plating aid solution to prevent re-oxidation of the substrate and enhance the adhesion of the zinc layer.
· Drying: Dry the steel grating plates to avoid zinc spitting during the immersion zinc process.
· Hot-dip galvanizing: Immerse the dried steel grating plates in molten zinc at approximately 450°C, where complex iron-zinc metallurgical reactions occur, forming a dense zinc-iron alloy layer on the steel surface.
· Cooling: After removal, let it cool naturally or cool with water to form a shiny silver-gray final appearance.
· Quality inspection and adjustment: Check the thickness and uniformity of the coating, and make adjustments for a few zinc nodules.

Classification of substrate materials
Low Carbon Steel (Q235B)	The mainstream material choice, accounting for over 95% of galvanized steel grating usage. Mechanical properties fully meet industrial requirements, with optimal cost-effectiveness, and it is the best match for hot-dip galvanizing process.
High Strength Low Alloy Steel (Q345B)	Used for special occasions with extremely high requirements for bearing capacity and lightweight design, such as long-span platforms. It has higher requirements for galvanizing process.

Features of Steel Grating - What is Steel Grating?
Steel Grating is welded bearing steel bars and cross twisted bars accoring to required pitch space between steel bars by steel grating welding machines.it is a grid building material.
All gratings are made using high quality standard steel materials which exhibit good hardness and high tensile strength. It is extremely strong, durable and corrosion resistance and great anti-slip performance.
Based on where the grating will be used and its load bearing requirements, steel bars are available in a range of spacing pitch, thicknesses and heights.

Surface Treatment Finishing of Steel Grating:
Generally Steel Grating is made with hot-dipped galvanized. Also zinc coating can be made according to the client's requirement.
Steel Grating can be called hot-dip galvanized steel grating,stainless steel gratings.Beautiful surface appearance and excellent performance in industry construction projects.

Materials of Steel Grating:
1) Carbon Steel Smooth Flat Bars,Carbon Steel Serrated Bars,I-Type Steel Bars.
2) Steel Twisted Square Cross Bars,Steel Round Cross Bars.
