Where METAPP® Decking Screw is Used?
Use-case:
/1
Fastening metal decking sheets to primary steel members such as hot-rolled beams and structural frames
/2
Composite floor deck installations where secure anchorage into thicker steel substrates is required
/3
Roof decking systems in multi-storey commercial and industrial buildings
/4
Applications requiring high drill capacity for penetrating heavy gauge steel without pre-drilling
/5
Structural decking connections where strong pull-out strength and vibration resistance are critical
Best-Fit Substrates:
• Hot-rolled steel beams (I-beam / H-beam sections)
• Heavy gauge structural steel
• Thick steel supports used in composite slab systems
Best-Fit Substrates:
• Hot-rolled steel beams (I-beam / H-beam sections)

Fastener Types
METAPP®
Fasten steel decking sheets to hot-rolled beams with superior engagement for maximum load stability.
The sealed fixing system ensures excellent weather protection and long-term durability.
Designed for high-performance structural applications where strength and reliability are critical.
Quality Checks
METAPP® decking screws undergo comprehensive quality evaluations to ensure reliable fastening and structural safety.
Each screw is checked for strength, precision, and long-term resistance in demanding applications.
Premium steel verified for consistent mechanical strength.
Heat treatment controlled to achieve required hardness.
Thread accuracy inspected for superior holding power.
Protective coating tested for corrosion resistance.
Drive performance and pull-out values validated.
How to Select the Right METAPP® Decking Screw?
Identify the deck material – Choose the screw based on steel deck profile and sheet thickness.
Match drill capacity – Ensure the drill point suits the supporting steel gauge for fast and secure installation.
Check fastening strength – Verify pull-out and shear requirements for structural stability.
Consider durability needs – Select proper coatings or sealing options for long-term corrosion resistance.
Installation guidance
Drive perpendicular to decking sheet and steel beam.
Tighten until EPDM washer seals without distortion.
