Key characteristics of seamless rectangular tubes

Seamless square rectangular tubes have excellent compressive strength, ductility, plastic deformation, and welding performance. They possess good ductility, and the aluminum alloy layer is firmly connected to the steel base, allowing for processes such as cold extrusion and cold rolling. They exhibit excellent compressive strength, ductility, plastic deformation, and welding performance. They have excellent plasticity. Cable bending and other forming processes do not damage the coating, making them suitable for general production processing, such as punching, laser cutting, welding, and cold drawing.

Key characteristics related to seamless square rectangular tubes:

1. Rust prevention and corrosion resistance - The galvanized layer, zinc-rich phosphating treatment layer, and electrostatic coating all have excellent rust prevention effects. Seamless square tubes can generally ensure no rust for thirty years in extreme environments.

2. Strong weather-resistant electrostatic powder coating process uses solid powder that solidifies at high temperatures. This powder characteristic is very stable for liquid building coatings, including architectural coatings. Therefore, seamless square tubes have excellent UV protection and will not fade under prolonged sunlight exposure.

3. Anti-disassembly: Anti-disassembly components are used for installation, and both the anti-disassembly components and the pipes have been tested by national technical units, with all indicators exceeding national industry standards.

Due to the requirements of the working environment, the plates of galvanized square rectangular tubes are mostly made of rectangular square tubes with hot-dip galvanizing, further enhancing corrosion resistance. To ensure welding quality, the hot-dip galvanized layer on the surface of the galvanized steel pipe should be removed before welding. This is to eliminate the whitening of the hot-dip galvanized layer in the welding and heat-affected zone, ensuring welding quality and good working conditions for employees. Naturally, seamless square tubes welded in this way can only be used in general working environments and are not suitable for work in corrosive environments.
