Cast-In Precast Concrete Anchors & Fixing Systems
Cast-in precast concrete anchors establish structural connections, shear transfer, and temporary or permanent fixing points across precast elements. Embedded directly into concrete elements during factory casting, these components convert localized point loads into distributed internal stress within reinforced concrete matrices.
Standard cast-in anchors eliminate structural post-drilling, avoiding rebar strikes and micro-cracking in high-stress zones. Raw material selection, hot-dip galvanizing or stainless steel metallurgy, head geometry, and precise embedment depths govern pull-out resistance, shear performance, and long-term durability under dynamic or static load conditions.

Concrete Shear Anchors
Engineered to resist parallel and perpendicular shear forces across panel-to-panel and panel-to-structure joints. Equipped with integrated shear lugs, ribbed shafts, or slotted plates, these units direct lateral loads away from the concrete boundary into surrounding stirrups and mesh reinforcement.
Precast Concrete Edge Anchors
Formulated specifically for close-to-edge placements, such as panel borders, spandrels, and thin slab edges. Specialized geometry-including flattened shanks, angled tail plates, and transverse reinforcement loops-prevents edge blowouts and concrete cone breakout under transverse tension or shear.
Cast-In Fixing Anchors
Internal threaded sockets (metric or coil threads) cast flush with the concrete surface. Designed for temporary rigging during erection or permanent attachment of MEP conduits, cladding brackets, structural steel lintels, and safety barriers. Supplied with plastic caps to preserve thread integrity during pouring and vibration.
Concrete Embed Anchors
High-tonnage tension anchors featuring forged footed ends, welded anchor plates, or wavy tails. Placed deep within the concrete core to maximize cone failure surface area, making them ideal for heavy structural connections, high overturning moments, and severe tension uplift points.
Heavy-Duty Concrete Anchors
Fabricated from high-tensile alloy steel or heavy-wall seamless tubing to handle combined high-tonnage tension and dynamic shear loads. Designed for infrastructure projects, bridge girders, crane runways, and high-impact industrial applications subject to fatigue and dynamic forces.
Structural Concrete Anchors
Primary structural ties designed for main frame connections: column-to-foundation, wall-to-beam, and panel-to-slab interfaces. Engineered to meet strict structural building codes for direct moment, tension, and shear transfer across critical precast joints.
Key Product Characteristics
Full Load Transfer via Direct Concrete Bonding: Forged heads, wavy ends, and cross-drilled tail pins distribute mechanical stresses through concrete compression cones rather than friction expansion.
Controlled Steel Metallurgy: Precision cold-headed or forged carbon steel (e.g., Q235B, Q355B, 20Mn2, 42CrMo) and austenitic/lean duplex stainless steel (AISI 304, 316, 1.4404, 1.4362) ensure predictable yield strengths and elongation parameters.
Corrosion Mitigation Systems: Surface finish options include plain black finish, electro-galvanizing (8–12 µm), hot-dip galvanizing (HDG per ISO 1461 / ASTM A153, ≥55 µm), and zinc-flake coatings (Geomet/Delta-Tone) for harsh atmospheric or de-icing salt exposure.
Dimensional Precision for Automated Production: Thread tolerances (Class 6H/6g) and controlled outer dimensions allow exact alignment with shuttering magnet adapters, rubber recess formers, and automated cage manufacturing workflows.
Ductile Failure Modes: Yield-to-tensile ratios prevent brittle steel shear before concrete cone capacity is fully utilized, ensuring predictable structural performance under overload conditions.

Architectural Wall Panels & Sandwich Facades
Edge anchors and shallow fixing sockets secure exterior insulated panels to structural frames. They accommodate differential thermal movement while handling out-of-plane wind suction and dead loads.
Structural Walls, Shafts, and Shear Panels
Heavy-duty shear anchors and cast-in connection loops link precast wall panels to floor slabs and adjacent shear walls. These anchors absorb lateral dynamic forces generated by wind or seismic activity.
Precast Beams, Girders, and Columns
High-capacity embed anchors absorb severe tension loads, moment transfer, and high shear forces during structural erection and long-term service life.
Retaining Walls, Culverts, and Infrastructure
Galvanized structural concrete embed anchors handle continuous earth pressure, ground moisture exposure, and cyclic traffic vibrations in bridge abutments, precast box culverts, and retaining walls.
Modular & Pod Construction
Compact fixing anchors integrated into precast bathroom pods, volumetric concrete modules, and staircase flights enable rapid mechanical rigging, temporary positioning, and final foundation bolting.
Selection & Design Considerations
Engineering Selection Process
Determine Loading: Tension, Shear, Combined Loading, Dynamic/Fatigue.
Evaluate Geometric Limits: Slab Thickness, Edge Distance, Anchor Spacing.
Assess Environmental Exposure: Dry Indoor, Humid, Marine Environment, De-icing Salts.
Verify Concrete Parameters: Compressive Strength (f'c), Cracked vs. Uncracked Concrete, Rebar Layout.
Final Specification: Material Selection, Surface Coating, Embedment Depth (hef), Head Geometry.
Critical Selection Criteria
Edge Distance (c1, c2) & Spacing (s1, s2): Placing anchors close to element edges reduces the effective concrete breakout cone area. Edge anchors or supplementary hair-pin shear reinforcement must be specified when nominal edge distances cannot be maintained.
Concrete Characteristic Strength (fck / f'c): Pull-out capacity scales directly with concrete compressive strength at the time of loading (e.g., early-stage stripping vs. 28-day 50 MPa final strength).
Cracked vs. Uncracked Concrete States: Tension zones subject to structural bending require anchors rated for cracked concrete conditions with lower effective capacity factors.
Combined Loading Interactions: Combined tension (N_Ed) and shear (V_Ed) forces must satisfy standard interaction formulas:
(N_Ed / N_Rd)^1.5 + (V_Ed / V_Rd)^1.5 ≤ 1.0
Environmental Exposure Classes:
• Indoor Dry (XC1): Electro-galvanized or self-color carbon steel.
• Exterior Atmospheric / Humid (XC3, XC4, XS1): Hot-dip galvanized carbon steel.
• Aggressive Industrial / Marine / Chloride Exposure (XS2, XS3, XF4): Stainless steel grade 316 / Duplex 2205.
Quality & Inspection
Quality Control Workflow
Raw Material Verification: Chemical analysis and tensile testing per heat lot.
Forming & Machining: Dimensional tolerances and thread gauge verification.
Welding & Assembly: 100% visual inspection, periodic NDT/MPI, and weld penetration checks.
Surface Finishing: Coating thickness measurement per ISO 2178 and salt spray testing.
Batch Mechanical Testing: Proof load tension, ultimate failure pull-out, and hardness checks.
Documentation Package: EN 10204 Type 3.1 material certificates, inspection reports, and factory CoC.
Inspection Standards
Material Integrity & Traceability: Raw steel bars and coils undergo spectrographic chemical analysis and heat-lot tensile testing before production. Every shipment includes EN 10204 Type 3.1 Mill Test Certificates detailing yield strength (ReH), ultimate tensile strength (Rm), elongation (A5), and chemical composition.
Mechanical Pull-Out & Tensile Proof Testing: In-house hydraulic test rigs conduct destructive tension and shear pull-out tests on anchors cast into standardized concrete blocks to verify characteristic failure loads, concrete cone breakdown, and steel rupture points.
Non-Destructive Testing (NDT): Critical structural welds on embedded plates and stud anchor assemblies undergo Magnetic Particle Inspection (MPI) or Ultrasonic Testing (UT) to identify internal voids, lack of fusion, or micro-cracking.
Coating & Thickness Verification: Galvanized layers are verified using magnetic induction coating thickness gauges (ISO 2178) to ensure compliance with the minimum 55 µm requirement for hot-dip galvanized finishes. Neutral Salt Spray testing (ISO 9227 / ASTM B117) monitors corrosion resistance performance across production batches.
