Door and window hardware can be divided into building door locks, handles, supports, hinges, door closers, handles, latches, window hooks, anti-theft chains, sensing door opening and closing devices, etc. Door and window hardware is a general term for various metal and non-metal accessories installed on building doors and windows. Assists in opening and closing doors and windows. This surface is usually electroplated or coated, sturdy, durable, flexible, economical, and aesthetically pleasing.

Profile wall thickness: From the appearance, for doors and windows of the same type, the external dimensions of the materials are the same, but the thickness of the materials is different. The input profile is 108 mesh, and the common wall thickness is 1.4mm. There are various specifications on the market, such as 1.6mm, 1.8mm, 2.0mm, etc. The thicker the contour, the higher the cost.

Different profile brands and raw materials: Due to different production equipment, the quality requirements for profiles produced by different manufacturers are also different, and the processing costs for profiles of the same specifications are also different.

They have the same color and function, but it is a well-known manufacturer's product that has been sold in the market for many years and enjoys a high reputation.

After the assembly of the angle steel is completed, the angle steel should be injected into the interior of the angle steel, and angle steel adhesive should be filled in the gap between the angle steel code and the profile to form a whole, that is, the connection is more firm, which can prevent angle steel leakage and improve air tightness.
