铝制钢型 2

描述

铝制钢型 2 is a carbon steel product coated with commercially pure aluminum through a hot-dip process. Unlike Type 1, which contains an aluminum-silicon alloy coating, this grade uses nearly pure aluminum to provide superior atmospheric corrosion resistance. It is widely used in construction, storage equipment, agricultural facilities, and outdoor structures where long-term durability is required.

涂料组合物

The coating of Aluminized Steel Type 2 mainly consists of aluminum with minimal alloying elements.

The high-purity aluminum coating forms a dense oxide film on the surface, protecting the steel substrate from corrosion and weather exposure.

机械性能

Mechanical properties are determined primarily by the base steel rather than the aluminum coating.

The material maintains good formability and can be processed through bending, roll forming, 冲压, 和焊接.

关键性能特征

出色的耐腐蚀性

The pure aluminum coating provides excellent protection against moisture, 氧化, and industrial atmospheres. This makes the material suitable for outdoor applications and environments exposed to humidity.

使用寿命长

A stable aluminum oxide layer continuously protects the surface from further corrosion, helping extend the lifespan of structures and fabricated components.

Good Weather Resistance

The coating performs well under long-term exposure to rain, sunlight, and temperature fluctuations. It maintains surface integrity better than ordinary carbon steel.

Excellent Heat Reflectivity

The bright aluminum surface reflects radiant heat efficiently, helping reduce heat absorption in buildings and industrial equipment.
