Manufactured under strict ISO 9001:2015 compliance, our roll-formed cold-rolled slotted angles, long-span steel decks, and pallet racks optimize horizontal and vertical cubic volume with full certification.
Founded in 2001, Guangzhou HEDA Shelves Co., Ltd. has grown into one of Asia’s preeminent manufacturers and global exporters of structural warehouse racking systems, slotted angle bars, boltless shelves, and multi-tier mezzanines.
Our in-house structural logistics engineers convert your architectural DWG or warehouse layout into full structural engineering calculations, 3D visual renderings, and complete Bill of Materials (BOM) within 24 hours.
Zero-Cost Engineering ConsultationEvery slotted angle section, structural upright, and beam weldment conforms to ISO 9001:2015 Quality Management System (Cert #18624Q00169R0M) and CE Marking for Construction Products (Cert #2435-CPR-8605159), meeting ANSI/RMI and EN codes.
Certified Quality AssuranceComponents are pre-bundled with protective air-cushion wrapping, metal corner protectors, and color-coded labels mapped directly to assembly drawings. Engineered loading optimizes container volume to lower landed freight costs.
Maximized Freight DensityA rigorous review of cold-rolled steel profiling, punch matrix geometry, moment distribution, and surface treatment integrity for industrial warehouse procurement professionals.
| System Classification | Yield Strength (Steel Grade) | Punch Pattern & Pitch | Standard Load / Tier | Corrosion Shield | Ideal Application |
|---|---|---|---|---|---|
| Light-Duty Slotted Angle | Q195 – Q235 (235 MPa) | Universal Slotted (50 mm) | 80 kg – 150 kg (UDL) | Electrostatically Applied Epoxy | E-commerce bin storage, spare parts retail |
| Heavy-Duty Slotted / Boltless | Q235B Cold-Rolled (235 MPa) | Teardrop / Butterfly (38/50 mm) | 300 kg – 800 kg (UDL) | Epoxy-Polyester Hybrid (60-80 µm) | Bulk boxes, heavy machinery tools, automotive |
| Long-Span Industrial Shelving | Q235B – Q355B (355 MPa) | Multi-Claw Pitch (50/75 mm) | 500 kg – 1,200 kg (UDL) | Pickling + Phosphating + Powder Coat | Distribution hubs, manual carton picking |
| VNA / Heavy Pallet Racks | High-Tensile Q355B (355 MPa) | Custom Omega Beam Interlock | 1,000 kg – 4,000 kg (UDL) | Hot-Dip Galvanized / Architectural Resin | High-bay pallet facilities, cold chain freezers |
Slotted angles undergo continuous progressive cold roll-forming rather than simple press braking. This process work-hardens corners, elevating tensile resistance along critical load lines and yielding cross-sectional stiffness that mitigates local buckling under asymmetric loads.
Zero-Deformation ProfilingEngineered punching dies maintain optimal steel net cross-sections. While continuous punch lines offer multi-point adjustability, improper slot spacing can compromise Euler column capacity. Our computerized CNC perforation preserves up to 88% effective net sectional area.
High Structural RigidityOur automated finishing lines utilize a 10-stage preparation protocol: automated alkaline degreasing, twin rinses, iron-phosphate nano-passivation, and automated electrostatic thermoset curing at 200°C. This eliminates pinholes and ensures superior salt spray resistance.
500+ Hr Salt-Spray RatingStrategic logistics planning requires supply chain buyers to look beyond raw steel weight. Modern procurement trends focus on agility, automation compatibility, and sustainability.
Modern distribution facilities increasingly deploy Autonomous Mobile Robots (AMRs) for floor-level carton and bin retrieval. Future slotted angle and boltless configurations must feature standardized base clearances, structural pick guides, and laser-guided reflective targets to support robot docking.
Automation-Ready InterfacesGlobal supply chain volatility has made containerized volumetric packing density a key metric in overseas procurement. Leading B2B importers prioritize precision nesting upright bundles and knock-down shelf panels that maximize 40ft High Cube container utilization up to 98%.
Max Freight EfficiencyStandardized, one-size-fits-all shelving is being replaced by site-specific engineering certifications. Turnkey projects now mandate verifiable structural calculations covering local seismic coefficients (Ss, S1), baseplate anchor pull-out ratings, and load-deflection ratios under L/200 limits.
Seismic Code ValidationGlobal procurement teams are prioritizing circular supply chains. Specifying scrap-recycled EAF (Electric Arc Furnace) steel along with low-VOC powder coatings helps international distribution networks meet Scope 3 emissions reporting and ISO 14001 sustainability targets.
Low-Carbon FootprintContinuous investment in automated production technologies provides measurable structural advantages across our standard and custom racking lines.
Traditional mechanical stamping can introduce micro-cracks and residual stress along slotted hole radii. Guangzhou HEDA employs high-speed automated CNC hydraulic punching lines that monitor punching shear forces in real time, delivering clean-cut edges and pitch tolerances within ±0.15 mm across the entire profile length.
Tolerances Within ±0.15mmSplicing angle bars lowers structural integrity and increases assembly labor. Our multi-stage rolling mills roll single-piece structural angles and shelf beams up to 12 meters in length. This unified cold-formed profile delivers uniform moment of inertia (Ix, Iy) across tall vertical runs.
Single-Piece Heights up to 12mStandard liquid dipping often leads to sagging, orange peel, and edge corrosion. Our automated powder lines use electrostatic corona charging guns in automated clean-room booths. The applied powder achieves uniform 60–90 µm cross-linked film thickness, offering high impact resistance against pallet strikes.
Impact-Resistant ShieldClear, technical answers to common questions on international compliance, load certifications, export packaging, and factory verification.
Safe working load capacity is calculated following RMI (Rack Manufacturers Institute) and EN 15512 specifications using Uniformly Distributed Loads (UDL). It accounts for effective unsupported column length, beam section modulus, connector shear stiffness, and an engineering safety factor of at least 1.65 to 1.92 against steel yield strength.
Yes. Our engineering department routinely works with both imperial (feet, inches, lbs) and metric (mm, kg) units. We output comprehensive 2D CAD DWG layouts, elevation prints, 3D BIM-compatible files, and itemized component schedules aligned directly with your local building codes.
Standard profile components ship within 10 to 15 business days. Custom cold-roll tooling, proprietary hole matrices, or custom architectural RAL powder colors typically require 20 to 25 business days, supported by our 30,000-ton monthly capacity across multiple roll-forming lines.
Uprights and angle posts are nested and steel-banded into solid structural bundles wrapped with multi-layer heavy-duty polyethylene stretch film, waterproof moisture-barrier lining, and corrugated edge guards. Beam connectors and hardware ship in reinforced fumigated wooden crates with internal desiccant bags.
We supply full Mill Test Certificates (MTC EN 10204 3.1) verifying steel chemistry and elongation, ISO 9001:2015 quality records, CE compliance documentation, powder coating salt spray reports, and third-party weld test reports (SGS / BV) to support local municipal permitting.
Bolted slotted angle uses M8 corner bolts and corner gusset plates, providing high static torsional rigidity and custom on-site fabrication flexibility. Boltless shelving utilizes teardrop or rivet keyhole connectors, assembling up to 75% faster without hand tools and enabling quick beam level reconfigurations.
