Specification for steel profiles
- Before 50, did not use 40 or 38, 10 years ago I have done spliced steel, and now who is willing to splicing ah. But really want to splice, and now have steel can also be spliced.s
Is the powder produced when the crushed plastic is crushed?
- Plastic crusher
Plastic crusher refers to the crushing of various plastic and rubber such as plastic profiles, pipes, rods, silk, film, scrap rubber products. Granules can be directly for extrusion, as the production of raw materials.s
The development of steel profiles
- From white to color: color profiles change the steel doors and windows in the past monotonous white, with the building as a whole with the perfect color. Color profiles market share rose rapidly, especially in some high-end residential area widely used.s
How plastic embossed profiles are made

PVC plastic profiles dip in the seam, how to deal with seamless docking
- Stabilizer too much or too little stabilizer is to inhibit the degradation, or with the release of hydrogen chloride reaction and to prevent the discoloration of PVC processing. Stabilizer according to the different types of different, but the total point, the amount of excessive will delay the material of the plasticization time so that the material export mold when the plastic is not, the formula system between the molecules are not fully dissolved, Its intermolecular structure is not strong cause. And the amount of too little will result in the formulation of relatively low molecular weight degradation or decomposition (also can be said to be plasticized), the stability of the intermolecular structure of the various components of the damage. So the amount of stabilizer will also affect the impact strength of the profile, too much or too little will cause the profile strength caused by the phenomenon of brittle profile.s
It is good for aluminum alloy
- It is also good for aluminum alloy.
The strength of the aluminum alloy is three times the strength of plastic, wind pressure strength than plastic two high. Aluminum alloy frame cross-sectional area of only steel 1/3, window frame weight is much lighter. Plastic doors and windows due to the strength of the material and low steel, although the steel lining by adding enhanced, but its wind pressure and watertight performance than the aluminum alloy window two levels. Just because the plastic window steel lining is not in its profile lap angle to connect the complete frame system, window frame, fan four corners and the T-shaped plastic angle of penetration is relatively low, so the high-rise buildings should be used with caution.s

Frame material is generally a bundle of four, or a bundle of six, the fan material is generally a bundle of 6-8, pressure line 20 - 30 bundles
What is the difference between plastic doors and windows and steel doors and windows?
- Through the cutting, welding, etc. made of doors and windows of the frame fan, equipped with sealing tape, tops, hardware and other accessories made of doors and windows, in order to enhance the rigidity of the profile, more than a certain length of the cavity need to add reinforced steel (steel Lining), this kind of doors and windows called plastic doors and windows.s
