The personage inside course of study points out: today, we are often able to see aluminum alloy scaffolding, the vast majority of the welding manufacturing. When using the welding technology of hot working in aluminum alloy material, can produce internal stress, easy to break aluminum internal molecular structure, reducing the original strength and durability, which requires the welding technology in production must have a strict quality control, otherwise easy to form a virtual welding, which has great internal stress, lead to products in the building after a certain height by shaking caused damage of products quickly.

So common aluminum alloy products such as aluminum alloy doors and windows, ladders, etc are all adopted the welding way of riveting. But as the company brand SPAN400 room types of aluminum alloy scaffolding, takes a different process. The company adopts a cold working method of aluminum alloy scaffolding, in terms of strength, stability, and durability, significantly better than common welding structure.

Such as mentioned above: aluminum alloy scaffolding, the English department has adopted cold bilges cold pressing process, can completely eliminate weld, does not change the molecular structure of the aluminum alloy material, ensure the strength will not reduce.

Such as SPAN400 non-welded series has adopted cold bilges cold pressing technology advantage, the framework of its producing and pull rod has the security thread surface, prevent slippery at the same time is also very durable. Based on other SPAN400 welding series of components, are all made of cold bilges cold welding technology manufacture, simple structure, combined with other components by the design, build all kinds of complicated deformed aluminum alloy scaffolding work platform of the structure of the system, can greatly improve the working efficiency.
