Our factory, established in 1998, has supplied reliable grating solutions to global markets, including North America, Europe, and Southeast Asia, with annual export values reaching US$5–10 million. This product combines the strength of Q235 steel with the corrosion resistance of hot-dip galvanizing, ensuring long-lasting performance in harsh environments.
Our BOLI MESH industrial platform grating is designed to provide superior load-bearing capacity, anti-slip safety, and easy installation. Whether you need a heavy-duty walkway, mezzanine floor, or trench cover, this welded bar grating offers a cost-effective solution without compromising on quality. Each panel is manufactured with precision welding and strict quality control, ensuring consistent dimensions and structural integrity.
Below we detail the key features, technical specifications, and advantages that make our product a preferred choice for industrial applications worldwide.
Key Features & Benefits
- High Strength Material: Made from Q235 steel (equivalent to ASTM A36), offering excellent tensile strength and weldability. Ideal for heavy-load industrial platforms, catwalks, and stair treads.
- Hot Dip Galvanized Protection: The entire grating is submerged in molten zinc, forming a thick, uniform coating that resists rust, corrosion, and chemical attack. Service life can exceed 20 years in normal outdoor conditions.
- Welded Construction: Load-bearing bars and cross bars are resistance-welded at every intersection, ensuring maximum structural rigidity and load distribution. No loose joints or weak points.
- Anti-Slip Surface: The flat bar surface, combined with optional serrated edges, provides excellent traction even in wet or oily conditions, enhancing worker safety.
- Customizable Dimensions: Bar height, thickness, mesh pitch, and panel size can be tailored to your specific load requirements and opening dimensions. We offer custom cutting and fabrication services.
- Easy Installation: Lightweight yet strong design allows for quick handling and installation. Standard panels can be bolted, welded, or clipped onto supporting structures.
- Low Maintenance: The galvanized coating requires minimal upkeep – simply wash with water occasionally. No painting or additional corrosion protection needed.

Detailed Product Description
The Q235 Steel Flooring Bar Grating from BOLI MESH is engineered to meet the rigorous demands of industrial environments. The bearing bars are manufactured from hot-rolled Q235 steel, which offers excellent weldability and strength. After welding, the entire grating undergoes a hot-dip galvanization process in accordance with applicable industry standards (such as ASTM A123 or equivalent). The result is a durable, corrosion-resistant product that can withstand heavy foot traffic, impact loads, and exposure to moisture, chemicals, and UV radiation.
Our welded construction method ensures that each cross bar is securely fused to the bearing bars, creating a rigid monolithic structure. This design distributes loads evenly across the panel, reducing the risk of bending or failure under concentrated loads. The open area of the grating allows for efficient drainage of water, oil, and debris, making it ideal for outdoor platforms, trenches, and drainage covers.
Safety is a top priority. The flat top surface of the bearing bars can be supplied with serrated edges (optional) to provide enhanced slip resistance. Additionally, the open design minimizes the accumulation of snow, ice, or dirt, reducing maintenance requirements. For applications requiring a flush surface, we can also provide recessed or counter-sunk mounting options.
Versatility in application: This product is widely used in oil & gas platforms, chemical plants, power stations, mining facilities, wastewater treatment plants, and commercial buildings. It serves as walkways, stair treads, mezzanine floors, bridge decks, security grilles, and trench covers. Our team can assist in designing custom layouts to fit your specific project requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the load capacity of your Q235 steel bar grating?
A: Load capacity depends on bar height, thickness, spacing, and span. For example, a grating with 40x5mm bars at 30mm spacing can support uniform loads up to 5 kN/m² over a 1m span. We can provide detailed load tables for your specific configuration.
-
Q: Can you provide serrated (anti-slip) bars?
A: Yes, serrated bearing bars are available as an option. The serrations are cut into the top surface to enhance grip, especially in wet or oily conditions. Please specify when ordering.
-
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 50 square meters for standard sizes. For custom dimensions or special requirements, the MOQ may be 100 square meters. However, we can accommodate smaller orders for sample or trial purposes – please contact our sales team.
-
Q: How long does the hot-dip galvanizing last?
A: In normal atmospheric conditions (rural or urban), the galvanized coating can last 20–30 years before requiring maintenance. In aggressive chemical environments, the service life may be shorter. We recommend a minimum coating thickness of 85 µm, and we can apply thicker coatings upon request.
-
Q: Do you offer different types of connection methods?
A: Yes, we can supply grating panels with pre-drilled holes for bolting, or we can weld clips or brackets directly. We also provide serrated locking bars and saddle clips for fast installation. Please advise your preferred fixing method.
-
Q: What is the typical lead time?
A: For standard sizes, lead time is 15–20 working days after order confirmation. Custom orders may require 25–30 working days, depending on complexity and quantity. Urgent orders can be expedited – please discuss with our team.
-
Q: Can you cut the grating to non-standard sizes?
A: Absolutely. We offer custom cutting, notching, and bending services. You can provide a drawing or specify dimensions, and we will fabricate precisely to your requirements. For complex shapes, a small setup fee may apply.
-
Q: How do you package the grating for export?
A: Panels are bundled with steel straps, separated by wooden spacers to prevent damage during transit. For small orders, we use plywood crates. We also offer rust-proof paper wrapping and plastic sheeting for extra protection. Packaging can be customized per your instructions.
