Galvanized Steel Grating

Galvanized steel grating is a load-bearing metal panel formed by high-pressure resistance welding of bearing flat bars and cross twisted bars, followed by full hot-dip galvanized anti-corrosion treatment. It features high load capacity, anti-slip performance, fast drainage and light self-weight, far superior to solid steel plates in ventilation and drainage efficiency. It is divided into plain grating, serrated anti-slip grating and compound grating, suitable for vertical and horizontal load-bearing platforms in indoor and outdoor corrosive environments.

Shunchen uses Q235B high-quality carbon flat steel as raw material, equipped with full-automatic CNC welding production lines and offline inspection stations. All finished gratings undergo full hot-dip galvanizing after polishing and pickling, zinc coating thickness strictly controlled in accordance with international anti-corrosion standards. Complete standard sizes are kept in stock, supporting customized width, length, flat bar thickness and spacing, plus edge wrapping, cutting and hole punching secondary processing. Our products pass third-party SGS and factory full inspection, fully meeting acceptance standards of domestic and overseas chemical, port and municipal projects.

Core Advantages and Selling Points

1. High Bearing Capacity & Efficient Drainage

Interwoven welded structure distributes pressure evenly without local deformation; open gaps achieve rapid rainwater and chemical liquid drainage, avoiding water accumulation and slippery hazards on platforms. Serrated surface option further improves anti-slip performance for wet coastal and chemical workshop scenarios.

2. Long-term Anti-corrosion Hot-dip Galvanized Treatment

Whole-piece hot-dip galvanizing forms compact zinc alloy layer tightly combined with steel base, effectively resisting salt fog, acid rain and chemical volatile corrosion. Service life reaches 10–15 years in coastal and chemical factory environments, greatly reducing later maintenance and replacement costs.

3. Light Weight & Easy Installation

Compared with solid checkered plates of equal load capacity, steel grating cuts self-weight by over 60%, lowering transportation and hoisting costs. Standard clamping accessories are matched for fast bolt assembly without complex welding on site, shortening construction period significantly.

4. Excellent Machinability & Customization Compatibility

Supports plasma cutting, saw cutting, bolt hole pre-drilling, edge closing and special shape processing such as arc, trapezoid and circular openings, adapting to irregular platform layout requirements of various industrial and municipal projects.

5. Complete Standard Compliance & Traceable Quality

All raw materials and finished products pass tensile, bending and salt spray testing; each batch provides mill test reports and SGS inspection certificates, accepted directly by overseas engineering supervisors without repeated third-party re-inspection.

Production Process and Quality Assurance

We adopt fully automatic numerical control high-pressure resistance welding lines for integrated forming of flat bars and cross bars. Semi-finished products go through burr trimming, surface pickling and flux treatment before whole-piece hot-dip galvanizing. Complete batch inspection includes dimensional tolerance detection, zinc coating thickness test, bending mechanical test and salt spray anti-corrosion test. Raw material chemical composition analysis and mechanical sampling test are carried out before production to eliminate internal defects such as cracks and uneven thickness. All production records are traceable by batch number; we can supply complete MTC mill test certificates, zinc thickness inspection reports and SGS third-party testing documents to meet global engineering filing and customs clearance requirements.

We prepare commercial invoices, packing lists, MTC material certificates, SGS inspection reports and zinc layer test reports to simplify cross-border customs clearance and project acceptance procedures.

Frequently Asked Procurement Questions

Q1: What is the difference between plain grating and serrated anti-slip grating for selection?

A: Plain grating has smooth surface, low cost, suitable for indoor dry factory passages; serrated grating has uneven tooth-shaped edges with higher friction coefficient, recommended for coastal rainy walkways, chemical oily platforms and stair treads to prevent slipping.

Q2: How to select flat bar thickness and mesh spacing according to load demand?

A: Light pedestrian loads adopt 3–5mm thick flat bar with 30×100 mesh; vehicle and heavy equipment loads require 6–10mm thick flat bar with 40×100 dense mesh. Our technical team provides free load-bearing calculation and specification matching suggestions based on your design drawings.

Q3: What surface treatment is recommended for coastal and chemical plant projects?

A: Whole-piece hot-dip galvanizing with zinc thickness above 85μm is mandatory for salt fog coastal areas and chemical volatile workshops; indoor dry temporary platforms can choose black anti-rust oil coated grating to control budget.

Q4: Can irregular-shaped steel grating be produced?

A: Yes. We support plasma cutting of arcs, circles, trapezoids and special openings matching pipeline layouts, and complete edge sealing processing to deliver finished panels ready for direct installation on site.
