What is the opening section of aluminum profile?

What is the opening section of aluminum profile?

Answer:

The opening position and the closed position are corresponding to the open section bar and the closed section section. Closed form refers to the outer contour of a profile forming a closed box shaped body; the opening is an outer contour without closure or no full closure. However, many practical profiles are more complex, with closed parts and open parts, which naturally produce "opening parts" and "closed parts"".The minimum column section thickness of the main stress parts, mainly referring to the national standard "Aluminum Alloy" building material GB/T5237 on the wall with a minimum thickness profile for 3.0mm, for the closed box section, with good resistance to local instability of the performance, can use a smaller wall thickness, the minimum wall thickness 2.5mm profiles, thus allowing.
Aluminum has an outer outline, an open outline, a closed outline, a plane to cut the opening, the plane is cut.Aluminum: aluminum, made from aluminum and other alloy elements. It is usually processed into casting, forging, and foil, plate, strip, tube, rod, section bar, etc., and then made by cold bending, sawing, drilling, assembling and coloring. The main metal element is aluminum, which is added with some alloying elements to improve the performance of aluminum. Aluminum products classification: rolling material, casting material, non heat treatable alloy, pure Aluminum Alloy (1 * * * Series), Al Cu alloy (2 * * * Series), aluminum manganese alloy (3 * * * Series), aluminum silicon alloy (4 * * * series of aluminum magnesium alloy (,) 5 * * * Series), aluminum magnesium silicon alloy (6 * * * Series), Al Zn Mg alloy (7 * * * Series), aluminum alloy and other elements (8 * * * series).
