4040 GB standard industrial aluminum profile is one of the most fundamental and widely used structural components in industrial manufacturing and automated equipment industries.

Specification Definition

It is square industrial aluminum profile with cross-section size of 40mm × 40mm, belonging to GB standard series. It features rectangular grooves, which is different from trapezoidal grooves of European standard profiles.

Material

Mainly made of 6063-T5 aluminum alloy; high-strength versions adopt 6061-T6. The surface is anodized to present matte silver white finish, featuring excellent corrosion resistance and easy cleaning.

Core Advantages

Light weight, high strength, modular assembly, reusable disassembly and reassembly without welding. It is the core material for lean production and equipment frame construction.

Section Design

Equipped with central round process hole and four square cavities around. Standard rectangular grooves fit GB standard T-nuts in M6 and M8 sizes.

Classified by wall thickness:

Light duty: 1.0-1.5mm

Medium duty: 1.8-2.0mm

Heavy duty: 2.5-3.0mm

Linear weight ranges from 1.48kg/m to 2.8kg/m, and load-bearing capacity increases with thicker wall thickness.

Key Performance Parameters

• Tensile strength: ≥160MPa (6063-T5), yield strength ≥110MPa, meeting torsion and compression requirements of general industrial frames.

• Surface Vickers hardness: ≥8HW, scratch-resistant and wear-resistant for harsh workshop environments.

Modular Connection

Quick assembly in vertical, horizontal and arbitrary angles via corner brackets, external and internal connectors. Its installation efficiency is much higher than traditional steel welding.
