Quality specification
Material:
Q345
All our frames and system scaffolds are manufactured of high
strength alloyed steel welded tubes. Chinese specification
is Q345 with following strength and elongation:
50,000PSI (345MPA) minimum yield strength,
68,150 – 91,350PSI (470-630MPA) tensile strength,
22% elongation.
Q235
Q235 is mostly often used to produce our scaffolding
accessories. It is Chinese specification for normal carbon
steel, with following strength and elongation:
34,000PSI (235MPA) minimum yield strength,
54,375 – 66,700PSI (375-460MPA) tensile strength.
Tube size:
Following tube sizes are available and used in different
markets for various products:
1.90”OD x 0.125”wall (48.3mm x 3.2mm)
1.68”OD x 0.095”wall (42.7mm x 2.4mm)
1.63”OD x 0.090”wall (41.3mm x 2.3mm)
1.26”OD x 0.078”wall (32mm x 2mm)
0.98”OD x 0.078”wall (25mm x 1.8mm)
0.98”OD x 0.070”wall (25mm x 1.8mm)
Powder coating:
EU’s RoHS standard compliant, to make sure no hazardous
substances is used or contained. Everything is environmental
friendly.
Hot dip galvanizing:
The process temperature is controlled well to ensure 420g/m2
zinc coating. In other words, 0.0024” (0.06mm) thick zinc
coating.
Dacromat:
Dacromat is a water-based, VOC
compliant coating, and comprised mainly of overlapping zinc
and aluminum flake in an inorganic binder.Salt spray test ranges from 480 to
1,000hours, depending on coat thickness.
