Q235 OUTDOOR Galvanized METAL IRON STAIR TREADS STEEL STEPS
Tread stair of steel grating is made from the steel grating (plain
style,serrated style and I
bar type) and to any dimensions to suit the relevant stairway.
Our stair treads have 8 types, they are:
1: Stair Tread without Nosing, Welding fixing
2: Stair Tread without Nosing, Bolted fixing
3: Stair Tread with Checkered Plate Nosing, Welding Fixing
4: Stair Tread with Checkered Plate Nosing, Bolted fixing
5: Stair Tread with Vertical Striped Plate Nosing, Welding fixing
6: Stair Tread with Vertical Striped Plate Nosing, Bolted fixing
7: Stair Tread with Perforated Plate Nosing, Welding fixing
8: Stair Tread with Perforated Plate Nosing, Bolted fixingYou can
choose any type above, and we also can supply customized products
ISO 9001-2000 manufacture and export steel tread, steel stair tread
, steel step, stair tread, steel ladder
Steel is high strength, light weight, strong stiffness, therefore
it is widely employed for the construction of large-span and
super-high, super-heavy buildings; it is the ideal elastomer with
perfect material homogeneity and isotropy which is most consistent
with the basic assumption of general engineering mechanics;
Material with perfect plasticity, toughness and large deformation
can receive dynamic loads well; short construction period; it is
widely used in Industrials, so it is available with high degree of
mechanization of specialized production; due to its high precision,
high efficiency, good airtight , it can be used to build tanks,
tanks and transformers. The disadvantage is poor fire resistance
and corrosion resistance.
1) Bearing bar (Load Bar)specifications(mm):
