Skills for purchasing fireproof windows
1. Process quality
High-quality steel fireproof doors are welded firmly and the welding joints are evenly distributed; the outer surface is sprayed flat and smooth; there should be product marks, quality inspection qualification marks and quality certification (approval) qualification marks in the specified positions. The appearance of qualified wooden fire doors should be complete, without damage, clean surface, without planing marks, burrs and hammer marks; the cutting corners and joints should be tight and flat; there should be product marks, quality inspection qualification marks and quality certification (approval) qualification marks at the specified locations.
2. Check the certificate
Fireproof windows are products included in the type recognition system. Products need to be inspected in type before sales. The general type inspection report describes the specifications, sizes, compositions, materials, and photos of the product in detail. When actually purchasing, you need to request a type inspection report from the manufacturer.
3. The dimensions of the qualified products of the logarithmic value
should be the dimensions of the sample description, the thickness of the door leaf should be the thickness of the door leaf in the sample description, the width of the door frame side wall should be the width of the door frame side wall in the sample description, the dimensions of the fireproof glass should be the dimensions of the fireproof glass in the sample description, and the thickness of the fireproof glass should be the thickness of the fireproof glass in the sample description.
4. The steel and wooden fire doors that meet the seal should be equipped with fireproof sealing strips. The sealing strip should be straight and without arches, and there should be a qualified inspection report issued by a national testing agency.
5. Look at the level
According to relevant standards, the safety levels of fire doors can be divided into Class A, Class B and Class C, among which Class C has the highest anti-theft performance, Class B followed by Class A and Class A are the lowest. Most of the things we see in the building materials market are Class A fire doors, which are more suitable for general household use.
Cleaning and maintenance of fireproof windows
1. When installing fireproof windows, you must carefully fill cement to effectively and closely combine the window frames with the walls. This can also maintain a reasonable coordination between the window frames and window frames, and use them for a long time without worrying about deformation.
2. When using neutral reagents or a cloth with moisture to wipe the surface of the fire-proof window, do not place it on the surface for a long time, otherwise it will infringe on the surface and cause the surface finish material to discolor or detach.
3. Remove stains on the surface of the fire-proof window and wipe them with a soft cotton cloth. It is easy to scratch the surface with coins. When the stains on the fast door are too heavy, you can use cleaning agents, toothpaste, special cleaning agents, etc. Wipe with clean water after decontamination and then dry.
4. When the fireproof window is closed, the resistance is too high. You can also apply a little lubricant to the movable lock tongue.
5. Pay attention to not rub too much at the edges and corners of the fire-proof window, otherwise the edges and skin layer will fall off.
