Irregular steel grating is a type of steel grating specifically designed to accommodate non-standard shapes, contours, and unique architectural or structural requirements. Unlike traditional rectangular or square grating, irregular steel grating offers flexibility in design, making it ideal for complex industrial, commercial, and infrastructural applications.

1. Specifications of Irregular Steel Grating

องค์ประกอบของวัสดุ

• Carbon Steel: Offers high strength and durability.

• Stainless Steel: Corrosion-resistant, ideal for harsh environments.

• Galvanized Steel: Provides rust resistance and extended lifespan.

• Aluminum: Lightweight and corrosion-resistant, suitable for specific applications.

Surface Treatment Options

• Hot-Dip Galvanization: Most common for protection against corrosion.

• Powder Coating: Available in various colors for aesthetic appeal.

• Paint Coating: Provides additional corrosion resistance.

• Mill Finish: Suitable for applications without additional coatings.

Load Bearing Capacity

• Designed to withstand specific loads based on material thickness, bearing bar size, and spacing.

• Heavy-duty options available for industrial use.

2. Models and Types

Based on Shape

• Circular Grating: Used for manholes, drainage covers, and round platforms.

• Triangular Grating: Often used in architectural applications.

• Trapezoidal Grating: Suitable for irregular floor spaces.
