Hollow aluminum bar for insuating glass
Apr 24, 2017

Hollow aluminum is one of the essential materials for the production of insulating glass, its quality is directly related to the use of insulating glass effect, the use of life and thermal insulation function. Its main role is to play in the insulating glass will be two or more pieces of glass evenly separated, the effective support of the role.

Common specifications: 4mm, 5mm, 5mm, 5mm, 5mm, 6mm, 6.5mm, 7mm, 8mm, 8.5mm, 9mm, 10mm, 11mm, 11.5mm, 12mm, 14mm, 14.5mm, 15mm, 16mm, 17mm, 18mm, 19mm, 21mm, 25mm and other specifications of aluminum, can also be customized according to the special needs of users.

Product technical requirements

Wall thickness

Single side wall thickness between 0.25-0.4, the surrounding wall thickness limit deviation of ± 0.025. The product is not allowed to have a hard bend, the side bend [except for free sagging curvature].


1. Surface smooth, rust, high corrosion resistance.

2. Aluminum surface through the hole through the uniform, good straightness, no deformation, dimensional stability.

3. High strength and toughness, and can be combined with bending equipment continuous bending into any angle of the aluminum frame.


 Mohs 5

raw material

To pure aluminum ingots as raw materials, the surface to be treated, so that no oxidation, corrosion and insulating glass used in other materials have excellent compatibility.

Product standards in line with: Q / TJXC1-2009
