Strict quality inspection

At our company, specializing in top-notch doors and windows with particular expertise in fireproof ones, strict quality inspection is non-negotiable. Right from the procurement of raw materials, we maintain the highest standards. The fire-retardant materials for our frames are carefully selected from reliable suppliers. They undergo initial laboratory tests to assess their resistance to high temperatures and mechanical strength.

During the manufacturing process, our seasoned quality control technicians are constantly on the prowl. For the glass panes, in addition to standard checks like clarity and flatness, we perform thermal shock tests to certify they can bear sudden temperature changes in a fire. The door and window hinges are tested for durability under extreme heat, ensuring they function smoothly even when flames are nearby.

Once the products are fully assembled, we conduct full-scale fire simulations. This allows us to gauge how effectively the fireproof doors and windows can block flames, smoke, and heat for the required duration. If any item fails to meet our stringent benchmarks, it is either reworked meticulously or discarded. This unwavering dedication to quality assurance means our customers can always rely on our fireproof products to safeguard their spaces.
