Second, purchase notice

Due to the different materials and specifications of various doors, the specific data confirmed with our customer service shall prevail! In addition, due to many product styles and colors, please contact customer service for more product styles!

Fire doors are particularly important as the first level of home fire protection , but when you buy a poor quality fire door, the fire door no longer fires. What should you do? Some unscrupulous manufacturers use honeycomb paper as a substitute for fire-resistant filling materials, which is cheap and does not play a fire-proof role at all. This is a joke in our lives. When we buy, the hardware accessories must also be fire-resistant hardware accessories.

There are five major ways to buy quality fire doors:

The first measure is to check the appearance . The high-quality steel \ fire door is firmly welded, and the welding points are evenly distributed. The outer surface is sprayed flat and smooth. The product mark, quality inspection qualified mark and quality certification (approval) qualified mark should be displayed at the specified position. The appearance of a qualified wooden fire door should be complete, without damage, with a clean surface, without planing marks, burrs, and hammer marks; cut corners and seams should be tight and smooth.

The second measure is the number . The overall dimensions of the qualified product should be less than or equal to the dimensions in the sample description. The thickness of the door leaf should be greater than or equal to the thickness of the door leaf in the sample description. The width of the door frame side wall should be greater than or equal to the width of the door frame side wall in the sample description. The overall dimensions of the fire-resistant glass shall be less than or equal to the outer dimensions of the fire-resistant glass as described in the sample description, and the thickness of the fire-resistant glass shall be greater than or equal to the thickness of the fire-resistant glass as described in the sample description.

The third measure is to look at the seals . Fireproof seals should be provided for qualified steel and wooden fire doors. The seals should be straight, without arches, and have a qualified test report issued by a national testing agency.

The fourth measure is to estimate the weight . Fire doors with qualified quality are generally heavier, while those with very light fire doors must be of inferior quality.

The fifth measure is to check the certificate . The fire door is a product that is included in the type approval system. Before the product is sold, it needs to undergo type inspection. The general type inspection report details the specifications, dimensions, composition, materials, and photos of the product. The type inspection report should be obtained from the manufacturer when the actual purchase.
