Production Process of Floor Decking

As a leading floor decking manufacturer and supplier in China, Tianjin SENBO Building Materials controls every step of production in our own factory. From raw material inspection to final packing, each sheet is processed under strict quality standards to ensure reliable performance for steel structure projects.

Below is a detailed look at how SENBO produces floor decking sheets for customers worldwide. If you need customized sizes, OEM profiles, or factory direct prices, contact our sales team anytime.

1. Incoming Material Inspection

Every steel coil entering our factory is checked before production begins. Our QC team tests:

• Sheet thickness
• Galvanizing coating weight
• Yield strength

Visual inspection is also carried out to reject any coils with rust, coating voids, or deep scratches. Only qualified raw materials move to the next stage. This step helps ensure the finished floor decking meets both project specifications and international standards.

2. Uncoiling, Feeding, and Leveling

The inspected steel coil is lifted by overhead crane onto the uncoiler. The strip is then fed through a multi-roll leveler to remove internal stress. Proper leveling prevents warping and side-bending after forming, which is important for keeping floor decking sheets straight and easy to install.

For certain deck profiles, a ribbing process is added. Small transverse ribs are pressed into the underside of the sheet. These ribs improve the mechanical bond between the steel deck and the concrete slab, which is a key advantage for composite floor systems.

3. Continuous Roll Forming

This is the core production step. The leveled steel strip enters a forming unit with multiple sets of rollers. Each roller group progressively bends the material into the desired shape, including:

• Rib height
• Rib pitch
• Effective width

SENBO’s CNC forming system controls speed and maintains tight tolerances. By changing roller sets, we can switch between open and closed deck profiles quickly. This flexibility allows us to offer more than 140 product models and support customized floor decking for different building designs.

4. CNC Flying Shear Cut-to-Length

After forming, the continuous sheet moves to the cutting station. Lengths are set according to engineering drawings. The flying shear automatically cuts each sheet when it reaches the correct position.

For special-shaped or complex deck panels, secondary cutting is done by plasma or laser equipment. All cut edges are deburred to reduce the risk of rust and to make handling safer for workers on site.

5. Finished Product Quality Inspection

Before packing, each batch of floor decking goes through a three-stage inspection:

Dimensional checks – length, rib height, pitch, effective width, and camber

Appearance checks – coating integrity, no cracks, dents, or zinc delamination

Spot checks – zinc coating weight and base metal thickness

This process ensures that every sheet leaving our factory is consistent in quality and ready for installation. It also reduces the chance of project delays caused by material defects.

6. Stacking, Packaging, Labeling, and Shipping

Finished floor decking sheets are stacked in layers with edge protectors and secured with steel strapping. Each package is clearly labeled with:

• Product model
• Sheet thickness
• Sheet length
• Batch number

Weather protection is applied before loading to prevent damage during transport. SENBO uses a professional 8-step packing SOP to minimize shipping damage and make unloading easier at your job site.
