Square pipe is a hollow square cross-section of light thin-wall steel pipe, also known as steel cooling curved profile. It is made of Q235 hot rolled or cold rolled strip or coil as the base material by cold bending processing and then high frequency welding made of square section shape and size of the section steel. In addition to the thickening of the wall, the corner size and the flatness of the edge of the hot rolled special thick wall square pipe reach or even exceed the level of the resistance welding cold formed square pipe. Good comprehensive mechanical properties, weldability, cold and hot processing properties and corrosion resistance, with good low temperature toughness.

Square tube is a name for square tube, that is, steel pipe with equal side length. It is made of strip steel by processing and rolling. Square tube: Generally, the strip steel is unpacked, flat, crimped, welded to form a round tube, and then rolled into a square tube from the round tube and cut to the required length.

Seamless steel pipes are perforated from whole round steel, and steel pipes without welds on the surface are called seamless steel pipes.
Seamless pipes are widely used, mainly for the manufacture of water wall pipes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, large and small smoke pipes and arched brick pipes.

Rock Wool Board is made from basalt, an inorganic raw material.
It is produced through heating basalt at 1350?C - 1400?C and transforming it into fibers,
which are bonded together using a thermosetting resin.
It is light and easy to install, mainly used for thermal and acoustic insulation where high compressive strength is required such as over-deck, floors, sandwich panels, and dry wall partitions.

Glass wool belongs to one category of glass fiber, which is a kind of artificial inorganic fiber.
Glass wool is a material that fiber molten glass into cotton.
Its chemical composition belongs to glass and is an inorganic fiber It has good molding,
small bulk density, high thermal conductivity, thermal insulation, sound absorption, corrosion resistance and chemical stability.

Water resistant board is easy to recognize with one side green color facing and backside with green color. It can widely apply to washroom, kitchen and other places where temperature change more.
