Will the model of steel profiles (such as 88-type extrusion profiles, 80 extrusion profiles) is based on what to develop ah
Strictly speaking, refers to the width of the bottom of the window frame profile. 88 is that the bottom of the frame width of 88 mm. And some profiles are not absolutely accurate, take the approximate value
The so-called 88,80,60, refers to the bottom of the profile width. The unit is millimeter. The profile manufacturers have these specifications are refers to the bottom of the width is the same, but different manufacturers of profile height is not exactly the same.
Press the bottom width.
Plastic steel profiles are made of polyvinyl chloride (PVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, UV absorbers, etc., by extrusion of the profile.
Ordinary steel profiles will be deformed, the color is relatively monotonous, usually white, if you want to change the color will add PVC with the film, a long time the PVC film will fade.
