Heavy-duty industrial trusses are not just "thickened versions" of ordinary trusses—they are specialized trusses designed exclusively for "high-load, long-term use" scenarios such as factories, warehouses, Square Truss for Event Stages and heavy equipment areas. Capable of stably supporting weights ranging from several tons to dozens of tons, they can also operate in harsh environments like oil contamination, vibration, and extreme temperatures for 5–10 years. For "heavy-duty tasks" such as suspending heavy robotic arms, building load-bearing platforms for production lines, and constructing large-scale storage racks, only these trusses can hold their own. Different industrial scenarios have varying "load directions" and "environmental conditions," Square Truss Rigging Hardware so the corresponding Truss types also differ. Avoid random selection: 1. Steel Heavy-Duty Square-Tube Trusses (Focus on "Powerful Vertical Load-Bearing")
Structural Features: Square-tube cross-section (300×300mm–800×800mm) with a wall thickness of 5–10mm. A "longitudinal stiffener" is added every 50cm inside, and a 300×300×20mm steel plate base is welded to the bottom (to increase ground contact area and prevent sinking into the ground).
Core Advantages:
Top-Tier Vertical Load-Bearing: Heavy-Duty Square Truss A 300×300mm model can withstand 6 tons with an 8-meter span (e.g., supporting 3 layers of heavy racks, 2 tons per layer); a 600×600mm model can withstand 15 tons with a 12-meter span (for hanging large crane accessories). Applicable Scenarios:
Logistics Warehouses: Load-bearing frames for heavy storage racks (3–5 meters tall, used for storing metal materials and heavy parts).
Factory Workshops: Operating platform frames for production lines (2 meters tall, capable of holding 6 workers + 3 tons of equipment), suspension frames for heavy tools (for hanging 5-ton hydraulic wrenches).
Note: If there is vibration in the workshop, place "rubber shock-absorbing pads" (10–15mm thick) under the bases to reduce vibration damage to the truss.
2. Steel Heavy-Duty Triangular Trusses (Focus on "Strong Torsion Resistance + Large Spans")
Structural Features: Square Truss Isosceles triangular cross-section (side length 300–600mm). Both the hypotenuse and right-angled sides are equipped with "cross stiffeners," and 15mm thick reinforcing plates are welded at joints to prevent stress cracking. Core Advantages:
Extreme Torsion Resistance: Heavy Duty Truss System A truss with a 10-meter span can hold a 4-ton fan and remain untwisted even in a level-5 side wind—30% more torsion-resistant than a square-tube truss of the same specification.
Flexible Spans: Can achieve a maximum span of 25 meters (with one support column added in the middle), suitable for large workshop spaces (e.g., a 15-meter-wide workshop, for building equipment frames spanning the entire workshop).
Applicable Scenarios:
Factory Workshops: Suspension frames Heavy Duty Truss System for heavy machinery (5-ton robotic arm rails), overhead conveyor frames in workshops (for hanging 2-ton conveyors).
Outdoor Industrial Areas: Maintenance platform frames for large equipment (8–12 meters tall), outdoor heavy-duty billboard frames (15–20 meter spans).
Key Requirement: For outdoor use, "Durable Truss Structure hot-dip galvanization + spray coating" (coating thickness ≥ 120μm) is mandatory to prevent rusting. In coastal areas, additional anti-salt spray coating is needed—otherwise, the truss will rust through within a year.
3. Special Alloy Heavy-Duty Trusses (Focus on "Extreme Environment Resistance")
Structural Features: Made of manganese steel or stainless steel (304/316L), with a mostly trapezoidal cross-section Industrial Truss Design and a wall thickness of 8–12mm. Welding is done via "argon arc welding + flaw detection testing" to ensure no cracks in welds.
Core Advantages:
Corrosion & Temperature Resistance: The 316L stainless steel version can be used in coastal factories (salt spray environments) for 10 years without rust; the manganese steel version works in cold storage (-30℃) or high-temperature workshops (50℃).
Ultra-High Strength: A 400×400mm model can withstand 8 tons with a 10-meter span, suitable for extreme scenarios.
Applicable Scenarios:
Specialized Factories: Equipment frames in chemical workshops (acid/alkali corrosion resistance), heavy-duty racks in food factories (easy-to-clean stainless steel), heavy-duty storage racks in cold storage (low-temperature resistance).
Outdoor Extreme Environments: Port equipment frames in coastal areas (salt spray resistance), maintenance frames for heavy mining equipment (dust resistance and impact resistance).
