Span of 40 meters, the height of the beam to support the 1.4 meter high density?
SC thick wall steel pipeSC, commonly known as black iron pipe, thick walled steel pipe laying or dark places require high strength, in many of the construction of floor walls.
The utility model has the advantages of high structure and material cost, easy aging, poor performance of the PVC tube and the problem of grounding, design and manufacture, etc., and is the patron saint of the electric wire and cable.
Building materials used in the field of electrical appliances, new technological breakthroughs in innovation, JDG galvanized steel pipe and thin wall steel pipe jumper wire connection should not use the complex structure of welding and metal conduit,
JDG is tightly connected to the socket of the tension steel conduit galvanized steel conduit (JDG catheter) is currently replacing the PVC pipe and other types of traditional SC electrical catheter replacement
