Open floor slabs Yx75-230-690 and Yx35-125-750 special-shaped steel plate

Description

1. YX75-230-690 open floor deck

Specification parameters

Wave height/wave distance/effective width: 75mm/230mm/690mm

Expansion width: 1000mm, utilization rate: 63.5%

Thickness range: 0.7-1.5mm (commonly 0.8mm, 1.0mm, 1.2mm)

Cross-sectional characteristics (taking 1.0mm thick as an example) :

Moment of inertia of the cross-section: 114.58 cm⁴/m

Section resistance moment: 27.20 cm³/m

Load-bearing capacity: During the construction phase, it can withstand a uniform load of approximately 2.5-3.5kN/m², and in the composite floor slab phase, it can reach 5-10kN/m².

Performance characteristics

High load-bearing capacity: Suitable for large spans (unsupported spans of 3-4 meters), and ideal for high-load scenarios such as industrial plants and sports venues.

Fire resistance performance: The open design requires additional fireproof treatment (such as spraying fireproof coating), with a fire resistance limit of 1-2 hours.

Convenient construction: Multiple layers can be laid simultaneously, shortening the construction period by 30%.

Economy

The unit price is approximately 50-80 yuan per square meter (with a thickness of 1.0mm), and the comprehensive cost is 300-500 yuan per square meter.

2. YX35-125-750 open floor deck

Specification parameters

Wave height/wave distance/effective width: 35mm/125mm/750mm

Expansion width: 1000mm, utilization rate: 75%

Thickness range: 0.7-1.2mm (commonly 0.8mm, 1.0mm)

Unit weight: 5.4-9.4 kg/m ³ (approximately 7.85kg/m ³ for a 1.0mm thick thickness).

Performance characteristics

Lightweight and economy: Light in weight (5.4-9.4kg/m ³), with a unit price of approximately 38.5 yuan per meter (1.0mm thick), suitable for budget-sensitive projects.

Applicable scenarios: Mostly used in commercial buildings and light factories with relatively small spans (requiring temporary support).

Versatility: It can be used as a roof panel, wall panel or floor deck.
