Fixed-tilt ground solar array with steel support members and foundation posts

Steel Supports for Solar Energy Projects

Racking, carport steelwork and foundations from our factories

We supply steel racking, carport frames, roof attachments and foundation components for solar projects. Packages can be grouped by array block, roof area or canopy, with the module attachments and supporting connections matched to each location.

Resolve the site interfaces before ordering components

Ground and foundation interface

Ground surveys and the foundation design set support positions and head levels. Racking variants then follow the accepted array layout rather than a single nominal project capacity.

Roof and building interface

Roof geometry, attachment locations and access need to agree with the building structure and roofing detail. The module layout must leave the required service and drainage routes.

Parking and envelope interface

Carports add vehicle clearances and foundation positions; BIPV adds building-envelope connections and drainage. These interfaces determine which structural and mounting parts belong in the purchase.

Support Steel and Mounting-System Requirements

ASCE 7 and the adopted building codeSite loadsThe project design uses the site loads and combinations for its mounting arrangement. Ground arrays, roofs and carports do not share one universal wind or snow rating.
UL 2703Module mounting and bondingWhere listing is required, identify the exact mounting system, module models and covered mounting or bonding configuration. A listed individual component does not establish acceptance for a different complete assembly.
ASTM A123 / ASTM A653Steel coating routeA123 applies to batch galvanizing of fabricated steel. A653 coating designations apply to continuously coated sheet. The component’s manufacturing route and exposure determine the specified protection.

Module, Rail and Foundation Connections

Module-to-clamp connection

Record the module make and model, frame dimensions, permitted clamp zones and attachment detail. Those references identify the rails, clamps and fastening arrangement.

Racking-to-foundation connection

The base or pile-head detail fixes the mating holes, bracket geometry and adjustment range. Ground reactions, soil conditions and installation verification determine the foundation purchase.

Racking-to-roof connection

Keep the roof fastener or clamp detail with the roof type and attachment position. Flashing, seals and drainage must match the building interface.

Count and pack the components

Our order list separates support members, rails, clamps, brackets and fasteners. Part numbers and row or roof-zone references carry through to the cartons and bundles.

Connection Fit and Component Inspection

Inspection by connection and component

Material and part identityMember and component records identify their steel or other specified material and the associated part number.
Mating holes and attachmentsRail brackets, clamps and pile-head connections follow the dimensional drawing for their matching parts.
Protection after fabricationCoating checks follow the material category, thickness and specified treatment; prepared connection surfaces retain their required condition.
Configuration and component countsThe released bill of materials ties each array block or roof zone to its members, clamps, brackets and fastening quantities.

Records for the selected mounting arrangement

  • Module model and mounting-interface details
  • Released array and component schedules
  • Foundation or roof connection drawings
  • Material and dimensional inspection records
  • Specified galvanizing or coating reports
  • Required system listing records and configuration references

Solar support and foundation procurement

Can roof and ground-mount components share one parts schedule?

They can be quoted together, with separate area and assembly references. Roof attachments remain linked to their roof-zone details, while ground-rack parts retain their foundation interfaces. Common module hardware is grouped only where its part identity and mounting requirements match.

Can you supply mounting components for an existing system?

Yes. We quote replacement parts from the original component drawing or an identifiable part reference. A material or geometry change is priced as a separate part; any effect on the mounting system's listed configuration is reviewed before that change is accepted.

Can one project include rooftop and carport supports?

Yes. Each location keeps its own structural and attachment details, module interfaces and component counts. The quote separates roof-area parts from the canopy members and mounting hardware.
