Broken bridge aluminum doors and windows are more and more favored by the market mainly due to their advantages of good thermal insulation, good rigidity, good fire resistance, large lighting area, and good atmospheric corrosion resistance, but not many people understand it.

This also makes many ordinary consumers seem very passive when they buy aluminum doors and windows with broken bridges due to the influence of information asymmetry. In this editor, we have compiled some basic knowledge about broken bridge aluminum doors and windows, so that you can better understand the product performance when purchasing.

Broken bridge aluminum doors and windows not only have good sealing performance but also are economical, and are welcomed by many families. Broken bridge aluminum doors and windows are inseparable from hardware accessories, including pulleys, slide rails, connectors, fixing bolts and crescent locks, etc. When choosing, special attention should be paid to whether the pulleys and slide rails are matched.

Pulleys are accessories that cannot be ignored in broken bridge aluminum doors and windows. The quality of the pulley is largely related to whether the doors and windows are easy to use. The quality of the pulley is determined by the quality of its outer wheel and bearing.

The outer wheels are generally made of high-strength wear-resistant nylon or iron. The iron pulley is relatively strong, but there is a sound when pulling; the nylon pulley has no sound when pulling, which is called a silent pulley and is widely used in the market.

The slide rails used for doors and windows generally have two types of rails, aluminum alloy and cold-rolled. The steel rail is strong and durable, and the aluminum alloy rail has less noise. When choosing, you should also pay attention to the thickness of the track.

If the doors and windows are small in size and light in weight, you can choose those smaller rails; if the doors and windows are heavy, you must choose thicker rails to ensure safety and durability.

Broken bridge aluminum doors and windows not only have good sealing performance but also are economical, and are welcomed by many families. This is inseparable from the important role of hardware. The above is a brief introduction to hardware by Baydee Upvc Profiles~
