Solar Structures & Carports

Product Introduction

01Product Overview

Steel solar carport structure with PV panels

A solar carport structure is a steel frame that turns a parking lot into a power-generating asset. The canopy roof carries photovoltaic panels while shading and protecting the vehicles underneath. As a dedicated solar carport manufacturer, BBN Steel supplies the galvanized steel frame only (or turnkey with panels), engineered for local wind, snow and seismic loads.

02Professional Solar Carport Structure Types

All types are PV-ready: roof purlins are reinforced for panel loading and pre-drilled for mounting clamps. Choose by your lot width, vehicle rows and local load code.

Single Cantilever

One row of columns, canopy cantilevered to one side. Lowest solar structure price, ideal for perimeter rows and narrow lots.

Double Cantilever

Two column rows with canopy between. Shades two vehicle rows, balanced cost and density for standard lots.

W-Type (double-sided)

Central column drives panels to both sides, maximizing PV area per footing. Best solar carport cost per kW.

A-Frame / Gable

Gable roof with clear span, snow-shedding slope. Strong for cold / high-snow regions.

Flat-Frame

Near-flat roof (≤2°) for optimal tilt brackets. Simple, fastest to install, lowest steel use.

Pipe Truss Canopy

Triangulated pipe truss for large clearspan (≥10 m) and heavy PV snow loads, used for bus / truck shelters.

03Applicable Building Scenarios

Our steel solar carport frames fit almost any paved lot. Common deployment scenarios:

Commercial Parking Lot

Retail, office and mall lots become shaded PV power stations. Reduce grid bills and offer EV-ready shaded parking.

Industrial Plant & Factory

Use rooftop-free ground space for self-consumption PV. Galvanized frames resist plant-area corrosion.

EV Charging Station

Combine PV canopy with chargers: solar powers the EVs directly. In-frame cable trays keep wiring clean.

Solar carport for logistics and warehouse

Logistics & Warehouse

Large flat lots at distribution centers are ideal for W-type double-sided arrays and pipe-truss canopies.

Residential Community

Quiet, low-profile flat-frame carports for apartments and gated communities with shared metering.

Highway Service Area

Cantilever canopies over fuel and rest bays; engineered for high wind and long service life.

04Steel Material & Grade Selection

We supply solar carport structures in the full range of structural grades. Grade is selected by span, load and local code — a key driver of solar structure price.

S235JR	EN 10025-2	235	EU-project secondary members
S355JR / S355J2	EN 10025-2	355	EU main frames, J2 for low-temp impact
S275JR	EN 10025-2	275	Balanced cost/Strength for mid loads

09FAQ

Q1How much does a solar carport structure cost?

As a reference, the steel frame only costs about USD 45–110 per square meter ex-works, depending on type (single cantilever is cheapest, pipe-truss canopy the highest). Your real solar carport cost also includes PV panels, foundation, transport and installation. Send us your layout and we return a fixed quote within 24 hours.

Q2What factors affect the solar structure price?

Main price drivers are steel grade (Q235B vs Q355B / S355JR), span and load (wind / snow), galvanizing thickness, and order quantity. Larger, standard-type orders lower the unit solar structure price significantly.

Q3Are you a solar carport manufacturer or a trading company?

We are a direct solar carport manufacturer with our own fabrication plant and QC team. You buy from the source, which is why our solar carport price is competitive and lead times are controllable.

Q4Can you customize span, height and local load codes?

Yes. Every project is engineered to your site: bay spacing, clear height, wind speed (up to 45 m/s) and snow load (up to 1.5 kN/m²) per GB, Eurocode or AISC.

Q5What is the lead time and minimum order?

Typical lead time is 20–45 days depending on tonnage; we accept small pilot orders (from 1–2 containers) and full commercial projects alike.
