The process of extrusion in aluminum usually involves the passage of a solid aluminum billet into a die. This is typically done with the assistance of a high-pressure hydraulic press, or ram, to force the block into the die.
When normal glass is broken, the edge is sharp and easy to cause damage to the human body. After the tempered glass is broken, the edge is smoother and less harmful to the human body. In the door and window industry, ordinary glass is gradually being eliminated, and tempered glass is becoming more and more popular. High-quality tempered glass has less impurities, no blistering, and smooth surface. It is safer in daily use of aluminium windows and doors.
In terms of wrought iron gate construction, U-frames or gate frames are the ‘backbones’ of gates and the metal frame pieces that go down the side and across the bottom of a gate. Different manufacturers take different approaches when it comes to U-frames, however, fully welded frames that go down the sides and across the bottom of a gate in a U shape will ensure the gate won’t sag.
Aluminum profiles are metal materials. Aluminum add various metal elements to make various alloys, which have advantages that other alloy profiles cannot match. Aluminum alloys has light weight and high strength, and can be extruded into a variety of complex cross-section profiles meeting the requirements of door and window design for various new sections.
