Plastic expansion pipe, from the beginning of the plastic era, some people use plastic columns instead of wood tenon (cork), with the changes of The Times, the building wall from the most soil wall, become harder, more solid, from the original iron nail has been unable to achieve a safe fastening effect, and with the cork installation, easy aging, cold shrinkage heat expansion can not achieve a long-term fastening effect. The plastic stopper installed on a variety of substrates can effectively improve the shortcomings of wood. At the same time, the density of plastic, shrinkage, toughness and so on are more accurate than wood materials, in the shape of the structure can also be ever-changing, according to the application of specific special-shaped, with a unique expansion tube. If the hardware fastening is the industrial rice, then the plastic expansion tube is the industrial dish. Feature

1. Generally, injection molding, agent plastic, two processing methods, agent plastic expansion tube modeling style is limited, most of the plastic expansion tube is molded by injection molding. Generally, PE, PA, PP three plastics are used as raw materials.

2. Plastic expansion pipe, also known as plastic expansion pipe screws, called by different places, commonly known as different, the north to expand the pipe, the south (Guangdong area) is used to colloidal or expanded colloidal name.

3. wall plug, Expansion pipe Tighten the plastic expansion pipe with screws. The correct matching of the plastic expansion pipe is the self-tapping screw with coarse teeth. Why is it recommended to use coarse teeth, because its fast teeth self-tapping screws are easy to cut into the expansion tube body, and even cut off the expansion tube, which does not achieve the best expansion effect.

4. Plastic expansion pipe can be matched with self-tapping screws, outer hexagonal self-tapping screws, cross countersunk head self-tapping screws, pan head self-tapping screws, outer hexagonal self-tapping screws, large flat head self-tapping screws, etc., the material is not limited. Applied to bathroom, wet places should choose stainless steel self-tapping screws.

5. Diameter M5, M6, M7, M8, M10, M12, M14, length from 20mm to 160mm or even more than 200mm. Commonly used dimensions are M6*30mm, M8*40mm,M10*50mm, M12*60mm.
Plastic anchors protect walls and wall hangings. When you need to hang something on a wall and there’s no stud in the right spot, plastic wall anchors may be the solution. Also called expansion anchors, they reinforce a screw in the wall surface so it can’t easily be ripped out.
