Steel Truss Floor Decking

Product Overview

The steel truss floor decking, also known as steel bar truss deck or composite steel decking, is a high-strength structural floor formwork system made from galvanized steel sheets and reinforced steel trusses. It is formed through precision cold roll forming technology and features a profile in V-shape, U-shape, trapezoidal, or similar wave-like sections. Designed primarily as a permanent formwork, it also serves as integral tensile reinforcement for cast-in-place concrete slabs, delivering enhanced structural stability and efficiency for modern steel frame constructions.

Product Features

Permanent Formwork & Reinforcement in One

Functions both as a formwork during construction and as a tensile reinforcement in service, reducing the need for extra rebars and concrete.

High Load-Bearing Capacity

The integrated truss design ensures excellent strength and stiffness, meeting the demands of heavy construction loads and long-span applications.

Galvanized Surface for Corrosion Resistance

Manufactured from galvanized floor decking material, the product is ideal for long-term use in humid, industrial, or coastal environments.

Excellent Concrete Bonding

Embossed surface patterns and stiffening ribs enhance mechanical interlock with concrete, improving shear resistance and integrity of the composite slab.

Quick Installation

Pre-fabricated panels allow for fast on-site assembly, reducing labor time and accelerating project schedules, especially for multi-floor buildings.

Supports Continuous Construction

Enables layer-by-layer concrete casting in high-rise structures, improving construction flow and reducing downtime.

Technical Performance

Dynamic Load Testing

Each batch undergoes dynamic shear-bond testing to ensure optimal composite performance under live load and span conditions.

Fire Resistance Certification

Fire tests up to 1.5, 2, and 3 hours under load confirm compliance with thermal insulation and load resistance in fire scenarios.

Cantilever Design Compatibility

For overhang conditions, the decking acts as permanent formwork. Cantilever length is calculated based on profile capacity. Negative reinforcements are required at supports as per structural engineer design.
