Comprises of plastic layer,binding layer and steel tube layer.It is fabricated with the same technique for internal/extemal injection composite metal plastic tube, the tube ends are sealed to isolate the internal wall from air and moisture so that the steel tube is not subject to rusting, which makes sure the tube material life is up to 10 years under normal condition, It is odor-free,toxic-free,low cost,easy to install,and is the ideal tube for greenhouse,telecommunications,logistics rack,etc.
Composite metal plastic tube(greenhouse)has the following advantage over galvanized steel tube(greenhouse):
1)No rusting on tube surface,both ends are sealed with rubber plugs to isolate air and moisture,which makes sure its service life is longer than 10 years without special maintenance.
2)Connection fittings are specially designed and some fittings are plastic coated to have better resistance against corrosion and rusting;single joint is used to connect all fittings and the installation is very easy.
3)Apart from making sure the steel tube framework has sufficient strength,it also significantly increases the frameworks toughness with high resistance against wind and snow.
4)The tube surface is smooth and will not damage the plastic film,which makes sure the film is good for long service life.
5)All colors and sizes are available on request.
