Welcome to Anping Xinye Metal Wire Mesh Products Co., Ltd, a trusted manufacturer based in Hengshui, Hebei, China. We specialize in high-quality steel grating solutions for demanding industrial environments. Our Hot Dip Galvanized Flat Bar Steel Grating for Heavy Load Applications is engineered to deliver exceptional strength, durability, and corrosion resistance, making it the ideal choice for heavy-duty platforms, walkways, and trench covers. With years of experience and a commitment to precision manufacturing, we ensure every panel meets rigorous performance standards.
This product is designed to support extreme loads while maintaining structural integrity in harsh conditions. The hot dip galvanizing process provides a thick, uniform zinc coating that protects against rust, chemicals, and weather, extending the service life far beyond ordinary painted gratings. Whether you need flooring for industrial plants, steel mills, or offshore platforms, our flat bar grating offers reliable performance with minimal maintenance.
Key Features & Technical Specifications
- High Load Capacity: Manufactured from strong Q235/Q345 steel, the flat bars are designed to withstand heavy static and dynamic loads, suitable for vehicle traffic and machinery.
- Hot Dip Galvanized Finish: The entire structure is hot-dip galvanized after welding, ensuring a corrosion-resistant coating that meets ASTM A123 standards. This treatment guarantees long-term durability even in wet or corrosive environments.
- Slip Resistance: The flat bar surface can be supplied with serrated edges or twisted cross bars to enhance traction, reducing the risk of slips in oily or wet conditions.
- Customizable Dimensions: We offer a wide range of bar heights (25–75 mm), thicknesses (3–6 mm), and mesh spacings (e.g., 30×100 mm, 40×100 mm). Panels can be cut to non-standard sizes, and special shapes such as cutouts for pipes or columns are available upon request.
- Easy Installation: Lightweight yet strong, the grating panels are designed for quick assembly using standard clips, welding, or bolting. Pre-drilled holes for fasteners can be provided.
- Low Maintenance: The galvanized coating requires no painting or frequent upkeep, saving labor and material costs over the product lifecycle.

The hot dip galvanized flat bar steel grating is widely used in heavy-duty applications such as industrial platforms, steel mill floors, offshore decks, drainage covers, and loading ramps. Its open design allows light, air, and water to pass through, reducing wind load and preventing accumulation of debris. The bearing bars are securely welded to cross bars using a resistance welding process, ensuring a rigid and stable structure that can support concentrated loads without deflection.
Advantages for Your Business
- Long Service Life: The hot dip galvanizing provides a protective barrier that lasts 20–30 years even in moderate industrial environments, reducing replacement frequency.
- Cost-Effective: Compared to stainless steel alternatives, our galvanized grating offers comparable corrosion resistance at a lower initial investment.
- Improved Safety: Optional serrated flat bars and anti-slip surfaces help prevent accidents in high-traffic zones.
- Eco-Friendly: Zinc coating is recyclable, and the steel itself can be recycled at end of life, supporting sustainable construction practices.

Frequently Asked Questions (FAQ)
-
What is the maximum load capacity of this grating?
The load capacity depends on the bar height, thickness, and spacing. For example, a 50 mm x 5 mm flat bar with 30×100 mm mesh can support up to 5 tons per square meter over a 1.5 m span. We provide detailed load tables upon request. -
Can I get custom sizes or cutouts?
Yes, we offer full customization. You can specify panel dimensions, bar sizes, and cutouts for pipes, columns, or manholes. Please provide a drawing or detailed description. -
How long does the hot dip galvanizing last?
In industrial indoor environments, the coating can last 20–30 years. In harsh outdoor or marine environments, the life may be 10–15 years. Regular rinsing can extend its life. -
Is the grating slippery when wet?
Standard flat bars are smooth; however, we can supply serrated (toothed) flat bars or add twisted cross bars to increase slip resistance. For maximum safety, we recommend specifying anti-slip options. -
What is the typical lead time for an order?
For standard sizes and quantities, production takes 10–15 working days. Custom orders may require 15–20 days. Urgent orders can be expedited upon request. -
Do you provide installation instructions?
Yes, we include installation guidelines with every shipment. We can also recommend suitable clips, welding methods, or bolting systems. -
How is the grating packaged for export?
Panels are bundled with steel straps and protected with edge protectors. For large orders, we use wooden crates or pallets to prevent damage during transport. -
Can I get a sample before placing a bulk order?
Absolutely. We offer free samples of 300×300 mm size. You only pay for shipping. Contact our sales team to request a sample.
