Product Description

Long span composite floor steel deck for multiple storeys

YX76-305-915 is one kind popular styles of metal deck. Compared to traditional decks,
this design is exceptionally resistant to compressive buckling resulting in superior span capability.Steel deck is green recycle construction material.MOQ: 500 square meters.

1.Steel deck basic information:
☆ Cross section drawing:


☆ Sectional properties:
 

Thickness (mm)	Yield strength (Mpa)	Weight (KG/M²)	I (cm^4/m)	I  (cm^3/m)
0.75	345	7.96	51.90	16.02
0.90	345	9.52	63.50	21.34
1.20	345	12.55	82.10	28.76
1.50	345	15.67	102.70	36.02

Note:This is calculated by standards Q345,we can also calculated by G550.

☆ Material details:
 

Thickness :	0.75 ~ 1.50 mm
Steel material :	High strength galvanized steel sheets
Material standards :	Q235, Q345, Q355, G550
Zinc coating :	120 ~ 275 g/m²
Length	Max 5.9 meters for 20FT container;
	Max 11.9 meters for 40FT container.

2.Steel deck advantages:

☆ Excellent bearing performance;
☆ Easy to be constructed and installed;
☆ It can improve shortcomings of traditional decks;
☆ Easy reinforcement,wiring,piping construction;
☆ It has nice and neat appearance.

3.Steel deck application:

The metal deck is mainly used as floor supporting in steel structure buildings,such as railway stations,exhibition centers,logistics centers,commercial high rise buildings,sports stadiums,etc.
