Shear Connectors Engineered for Reliable Composite Floor Performance.

Shear connectors are critical structural components that create the bond between steel beams and concrete slabs in composite floor systems. Welded directly onto steel beams, these high-strength headed studs transfer shear forces between steel and concrete, enabling both materials to act as a single integrated structural unit. Designed for superior load transfer, structural stability, and long-term durability, Alfaa PEB shear connectors are manufactured for reliable composite action in commercial buildings, industrial facilities, warehouses, and multi-storey steel construction projects.

Advantages

Advantages of Shear Connectors.

01/01

Shear connectors are used in composite floor construction to create a strong bond between the steel beam and concrete slab. They help transfer shear forces, improve structural strength, reduce material usage, and support faster construction in steel decking and composite slab systems.

Alfa PEB shear connectors are suitable for steel beams, decking sheets, mezzanine floors, composite slabs, industrial platforms, commercial buildings, and PEB projects where high strength, faster installation, and reliable structural performance are required.

Advantage	Short Description
Easy to Use	Simple installation process suitable for steel decking and composite slab construction.
Fast Installation	Pre-set welding parameters help speed up installation compared to conventional methods.
Economical Solution	Helps reduce concrete and steel usage, supporting cost-effective floor construction.
Minimum Site Intervention	Requires less manual work and supports faster execution at site.
Through Deck Welding	Can be welded through formed galvanized decking sheets directly onto steel beams.
Improved Structural Strength	Provides strong shear transfer between steel beams and concrete slabs.
Faster Construction Speed	Supports quicker slab casting and overall project completion.
Reduced Floor Section	Helps optimize floor design and reduce overall floor depth in composite construction.

Comparison

Comparison: TR60 vs TR80 Metal Deck Sheets.

02/03

TR60 and TR80 metal deck sheets are composite floor decking profiles used for mezzanine floors, industrial platforms, commercial buildings, warehouses, and PEB structures. TR60 is suitable for standard composite floor applications, while TR80 is preferred for deeper profile requirements, longer spans, and higher load-bearing performance.

Feature	TR60 Metal Deck Sheet	TR80 Metal Deck Sheet
Profile Depth	60 mm	80 mm
Overall Depth	Approx. 72 mm including re-entrant profile	Approx. 92 mm including re-entrant profile
Span Capability	Suitable for standard spans	Suitable for longer spans
Load Capacity	Medium load capacity	Higher load capacity
Beam Requirement	May require more secondary support	May require more secondary support
Effective Cover Width	666 mm	600 mm
Ideal Use	Standard buildings, mezzanine floors, commercial slabs	Large-span structures, industrial platforms, heavy-duty floor systems

FAQ's

They transfer the longitudinal shear force at the steel-concrete interface that makes composite action possible. Without them, the beam and slab work independently — inefficiently. With them, they work as one structural system with up to 50%+ greater capacity than the steel beam alone. Every composite floor's structural efficiency depends directly on its shear connectors performing as designed.

Partial composite uses fewer connectors — typically 40–75% of the full composite requirement — to develop a proportional share of maximum composite capacity. It is frequently more economical: even 50% composite action captures the majority of the structural benefit at lower connector cost. The structural engineer calculates the optimum degree of compositeness for each beam.

By drawn arc stud welding — a single high-energy weld cycle that fuses the connector base to the beam flange in under one second. For composite deck applications, through-deck welding welds the connector directly through the decking sheet to the beam flange below. Post-weld quality is verified by a 30° bend test on a sample from each welding session.

19mm is standard for most commercial and multi-storey applications. 22mm delivers higher individual connector shear capacity and is specified for heavy industrial beams, longer spans, or where the structural engineer requires greater per-stud capacity to reduce connector count. Shank height is selected based on deck profile depth plus minimum concrete cover above the connector head.

Mill test certificates confirming material grade, chemical composition, and mechanical properties; dimensional inspection records; and product data sheets. Full material traceability to structural as-built records is available for projects requiring third-party certification or specific quality documentation standards.
