Hot-dip galvanized steel pipes are a type of composite steel pipe, so the quality of hot-dip galvanized steel pipes must be determined by assessing the base material and the quality of the plastic coating.

Steel Pipe:

(1) Seamless, verifiable in well-lit areas.

(2) Excellent resistance to compression, not prone to deformation.

(3) Strong mechanical properties; will not break during the expansion test.

(4) Provided with warranty certificates for fittings and inspection reports.

(5) Free of burrs and other contaminants; the interior is clean and smooth.

(6)钢管 is made of carbon steel without impurities, offering excellent hygiene.

2. Plastic Coating:

Exquisite finish and meticulous craftsmanship, free of burrs.

(2) The internal electrostatic powder coating process employs electrostatic adhesion to bond epoxy resin powder to the inner and outer walls of steel pipes, resulting in a durable and hygienic finish that is non-toxic and environmentally friendly.

(3) The exterior electrostatic powder coating of polyethylene has a glossy finish, excellent adhesion, tough surface, wear resistance, and smooth texture. It is capable of withstanding low temperatures and preventing corrosion.

(4) Odorless and free from刺激性 odors.
