1. Steel Structure Frame for Conveyor Systems

Steel structure frames are characterized by high strength, light weight, good overall stiffness, and strong resistance to deformation — making them especially suitable for enclosed belt conveyor galleries and transfer towers. Combined with galvanized Rain Covers, these frames provide weatherproof bulk material transport in exposed mining and port terminal environments.

Steel offers excellent homogeneity and isotropy, aligning with fundamental engineering mechanics assumptions. Its plasticity and toughness allow it to withstand dynamic loading from Conveyor idlers and material impact. For large-span conveyor galleries, high-strength H-beam and T-shaped steel varieties are recommended. Rain cover options include galvanized steel, aluminum, stainless steel, fiberglass, and sliding canvas — protecting both material and equipment in all weather conditions.

2. Key Features of Steel Structure Frames

High Material Strength, Light Weight — Steel's high strength-to-weight ratio reduces foundation requirements for long-span conveyor galleries, especially in elevated transfer tower configurations.

Excellent Toughness & Plasticity — Uniform material properties ensure high structural reliability under dynamic loads from belt movement and material impact at loading points.

High Mechanization — Prefabricated steel frame components enable rapid on-site assembly with bolted connections, significantly reducing construction time for cement plant and coal handling conveyor lines.

Heat Resistant, Not Fire Resistant — Steel frames maintain strength at elevated temperatures but require fireproof coatings when used in coal and power plant environments with combustible materials.

Low Carbon & Reusable — Steel is fully recyclable, supporting sustainable construction practices. Combined with modular rain covers, the entire conveyor enclosure can be disassembled and relocated for aggregate quarry and temporary site applications.
