Black hollow section specification:

Size:12x12-500mm; thickness: 0.6-20mm

Material grade:Q195-q235

Product usage:Used for construction

Black hollow section advantage:

• High durability

• Perfect resistance to corrosion and rust,suitability for sea area's construction (high oxidation)

• Black RHS (Rectangular Hollow Section) Pipes are strength and economy

• Black SHS (Square Hollow Section) Pipes are balanced strength, symmetry and aesthetics

Black hollow section application:

Hollow structural section (HSS) is a metal with a hollow tubular section. These sections can be round (CHS), square (SHS) or rectangular (RHS).

Black Steel Square Pipes are widely used in construction works, such as workshop, interior, scaffolding,mechanical manufacturing.
