Hot Dipped Galvanized Steel Perforated Slotted Angle Iron Gi Angles Steel bar for Garage Door

Product Description:

Punched angle steel is a structural steel material that is punched on the surface of angle steel according to predetermined specifications and arrangement. It combines the structural strength of angle steel with the functionality brought by punching, and is widely used in engineering scenarios that require connection, fixation, ventilation, or weight reduction.

Punching angle steel is made of hot-rolled equal or unequal angle steel as the base material, and common materials include carbon steel such as Q235B and Q345B, as well as low-alloy high-strength steel. Process circular, square, or other shaped holes on the wing edge through punching technology. These holes are mainly used for installing bolts, screws, or other connectors, achieving quick assembly and flexible adjustment. They are also commonly used for cable threading, ventilation and heat dissipation, or reducing the weight of components.

Features:

High strength and corrosion resistance, usually made of high-quality carbon structural steel or stainless steel such as Q235B, with good mechanical properties; The surface can be treated with hot-dip galvanizing, spraying, etc. to enhance its corrosion resistance.

Multiple specifications are available, and edge width, thickness, aperture, spacing, and arrangement can be customized according to needs to adapt to different engineering scenarios.

Reducing self weight and optimizing the structure, the through-hole design effectively reduces material usage and overall weight while maintaining sufficient rigidity, making it suitable for weight sensitive structures.

Easy to install and wire, preset punching for cable threading, bolt positioning or modular assembly, improving construction efficiency.

Supporting the upgrade of composite materials, some new punched angle steels use composite materials such as FRP (fiber-reinforced plastic) to achieve insulation, rust resistance, lightweight and high strength characteristics, suitable for special environments such as photovoltaic brackets and distribution boxes.

High processing accuracy, modern CNC punching technology ensures accurate hole position, no burrs on edges, reduces stress concentration, and extends service life
