Fiberglass grating with a concave surface is a type of molded fiberglass-reinforced plastic (FRP) grating designed to provide a combination of slip resistance, structural strength, and long-term durability. The concave surface is created by the natural cooling and curing process during molding, which results in a slightly textured, curved surface across the bearing bars. This surface design offers improved slip resistance compared to smooth surfaces, while being less abrasive than gritted finishes, making it suitable for both industrial and pedestrian use.

产品描述

The concave surface on fiberglass grating is not an added material or coating but an inherent feature of molded FRP grating. As the resin and fiberglass cure inside the mold, the top surface forms a slight inward curve along each bearing bar. This design increases surface contact and traction underfoot, especially in wet or damp environments.

Available in various mesh patterns such as 38x38mm (1.5"x1.5") or mini-mesh styles, fiberglass grating with a concave surface is offered in multiple resin types including general-purpose isophthalic polyester, chemical-resistant vinyl ester, and fire-retardant phenolic. Common panel sizes include 1220x3660mm (4'x12') and 1000x4000mm (1m x 4m), with thickness options ranging from 25mm to 50mm depending on load requirements.

Key Applications

Fiberglass grating with a concave surface is used in many sectors where moderate slip resistance, corrosion resistance, and ease of maintenance are critical. Its key applications include:

• 化工厂: Used for walkways and platforms where chemical exposure is frequent and slip resistance is important.
• Wastewater Treatment Facilities: Ideal for high-moisture environments where rust-free, non-slip grating is needed.
• Marine & Offshore Applications: Suitable for ship decks, piers, and docks where sea spray and water exposure are constant.
• 食品加工: Used in areas where moderate cleaning and traction are needed without the abrasiveness of gritted surfaces.
• Pulp & Paper Mills: Deployed in production areas with wet floors and chemical exposure.
• 公共基础设施: Installed in parks, pedestrian bridges, and industrial staircases requiring safe, low-maintenance surfaces.

优点

• 防滑: The concave profile provides reliable anti-slip performance under normal foot traffic, reducing the risk of slips in damp or humid conditions.
• Comfortable Underfoot: Less abrasive than gritted surfaces, making it more suitable for areas where people may kneel, sit, or walk for extended periods.
• 耐腐蚀性能: Made from FRP materials that resist chemical attack, saltwater, and UV radiation, far outperforming steel in harsh environments.
• 非导电: Safe for use around electrical systems and in high-voltage areas due to its non-metallic, non-conductive nature.
• 轻的: Easier and cheaper to handle and install compared to metal grating, reducing labor and transportation costs.
• Long Service Life: Resistant to impact, weather, and corrosion, requiring minimal maintenance over time.
