Procedure
Hot-dipped galvanized, electro-galvanized, and spraying brushing and soaking. Anti-acid and alkali corrosion capacity in the range PH6 to PH12.5. A stable protective film will be formed on the zinc surface, providing good anti-corrosive properties.
Type
- Flat bar: plain type, plain I type, serrated type, serrated I type
- Cross bar: round type and square twisted type
Finishing Treatment
Steel grating untreated: Allows quicker delivery to customers who fabricate and galvanize the grating on their own.
Galvanized: Hot Dip Galvanizing provides a hygienic, clean, maintenance-free bright finish.
Packing
Steel grating is normally packed in piling up ways with two pieces of square wood on both upper and bottom sides. There are four or six pieces of M10 long bolts penetrating the gratings and screwing together. This packaging is suitable for loading and unloading by forklift and crane.

Frequently Asked Questions
What materials are used for steel grating?
Steel grating is commonly manufactured from carbon steel, galvanized steel, stainless steel, and aluminum. Carbon steel grating is the most economical option, while stainless steel provides excellent corrosion resistance.
What is galvanized steel grating?
Galvanized steel grating is carbon steel grating coated with zinc through a hot-dip galvanizing process. This coating improves corrosion resistance and extends the product's service life in outdoor and industrial environments.
What are the advantages of steel grating?
Steel grating offers high strength, excellent load-bearing capacity, anti-slip performance, good ventilation, easy drainage, low maintenance, and long service life.
What industries commonly use steel grating?
Steel grating is widely used in construction, oil and gas, chemical plants, power stations, shipbuilding, mining, wastewater treatment, food processing, and transportation industries.
How do I choose the right steel grating specification?
The correct specification depends on load requirements, span length, environment, surface treatment, and application type. Factors such as bearing bar size, spacing, and thickness should also be considered.
