Mining Conveyor Gallery Steel Structures
Steel conveyor galleries and trestles for mining and mineral processing sites: angle steel and pipe truss galleries on bolted trestles, with walkways, gratings and cladding, galvanised or coated for abrasive dust and shipped in marked segments for remote sites.
What Conveyor Gallery Projects Demand From the Steel
Long elevated runs, dust, wind and remote sites decide the design more than the belt itself.
Long elevated runs across uneven ground
Truss galleries in angle steel or circular pipe span between bolted trestles set to the ground profile; truss depth and chord sections follow the span and the belt and walkway loads.
Abrasive dust and open exposure
Hot-dip galvanising to the specified coating mass or ISO 12944 coating systems selected for the site, with dry film thickness recorded; cladding and roofing are quoted where the gallery is enclosed.
Remote sites with limited erection capacity
Galleries and trestles are fabricated in bolted segments sized for containers or flat racks, trial-assembled in the yard and shipped with marked members and erection drawings so local crews bolt them up without site profiling.
Walkways that must meet safety rules
Walkways, gratings, handrails and stairs to the safety standard your project specifies, detailed with the truss so hanger points and access are on the drawings rather than added on site.
How Your Project Is Built
Three phases from the first drawing to handover. Move over a phase to see what happens in it and what you receive at the end of it.
Engineering & Foundation
The structure is sized in a 3D BIM model before any steel is cut. While members are fabricated in the factory, earthworks and independent foundations are poured on site in parallel from the anchor bolt templates we ship first.
- 3D BIM model before any steel is cut
- Anchor bolt templates shipped first
- Foundations poured in parallel with fabrication
Fabrication & Erection
Columns, beams and trusses are CNC-cut, welded, tested and trial-assembled in the yard, then shipped in erection sequence. On site the frame is bolted from marked members with the erection drawings and our remote or on-site guidance.

Envelope & Handover
Cladding, insulation, openings and rainwater goods close the building; dimensional and coating records are handed over with the as-built drawings and the certificate package.

Technical Parameters
What the gallery is sized from, and what is fixed before fabrication.
| Parameter | What it is set from |
|---|---|
| Gallery format | Angle steel or circular pipe truss galleries on bolted trestles; enclosed or open as specified |
| Loads | Belt, idler and material loads from the conveyor supplier, walkway live loads, wind and seismic loads for the site |
| Span and trestle spacing | Set from the ground profile and the truss depth; splices at bolted panel points |
| Access | Walkways, gratings, handrails and stairs to the specified safety standard |
| Corrosion protection | Hot-dip galvanising to the specified coating mass or an ISO 12944 system for the site, DFT recorded |
| Trial assembly | Truss segments trial-assembled in the yard with bolt hole groups checked for at least 95% free entry and a dimensional report before coating |
| Execution class | EN 1090-2 EXC2 (certificate 2787-CPR-01627) |
| Lead time | 40 to 50 days for a typical single-building portal frame scope: 1–2 weeks to shop drawings for your approval, then 4–5 weeks for fabrication, coating and loading; larger or multi-building projects are phased by building |
| Documentation | MTRs, WPS/PQR, welder certificates, NDT and DFT reports, erection drawings and the certificate package with every shipment |
Recommended Product Systems
The structural systems we fabricate most often for this kind of project. Each opens the product page with sub-systems, parameters and FAQ.
Multi-storey steel buildings from one fabricator: thick-web H and box columns, cruciform columns, steel floor beams, composite decking and stairs for commercial and industrial frames, with embedded parts and anchor bolts shipped ahead of the steel.
Pre-engineered buildings on a steel portal frame, the rigid frame building type of every PEB catalogue: tapered H-section primary frames, cold-formed purlins, bracing and anchor bolts detailed as one system for workshops, warehouses and agricultural halls.
Steel truss structures for long-span roofs: circular pipe trusses, square tube trusses, angle steel trusses and H- or I-beam trusses fabricated as roof truss systems for terminals, stations, industrial halls and exhibition centres.
Building envelope systems quoted with the steel frame: roof and wall cladding, insulation and waterproofing, industrial doors, windows, louvers and ventilators, gutters and downspouts.

Frequently Asked Questions
What do you need to quote a conveyor gallery?
The conveyor route and ground profile, belt width and the loads from the conveyor supplier, whether the gallery is enclosed, site wind and seismic data, and the required walkway arrangement.
Angle steel or pipe truss for the gallery?
Angle-section trusses are the economical choice where the gallery is bolted on site; circular pipe trusses suit longer spans and exposed structures. Send the span and we propose the format with a BOQ.
How are galleries shipped to a remote mine site?
In bolted segments sized for containers or flat racks, trial-assembled in the yard and shipped with marked members, erection drawings and spare fasteners.
Do you supply the walkways and gratings?
Yes — walkways, gratings, handrails and stairs to the specified safety standard are detailed with the truss and quoted in the same package.
Which coating suits a dusty, open-pit environment?
Hot-dip galvanising to the specified coating mass for most galleries, or an ISO 12944 system selected for the site where painting is specified, with dry film thickness recorded per member.
Can you erect the gallery on site?
Your local contractor works from our erection drawings and marked members with remote guidance included; on-site supervision or a full erection team can be provided for complex or remote projects.
