Steel Single Post Solar Carport Mount

The Steel Single Post Solar Carport Mount from China Xiamen Honor Energy reduces dependence on fossil fuels and lowers carbon emissions and also provides shade and rain protection for vehicles, extending their service life. Not only can it be paired with energy storage systems to serve as an emergency power source, but it also enhances the green image of enterprises and industrial parks.

Unlike double-post designs, the carport places a single column between two bays, with a cantilevered beam extending up to 5.5 meters—full door-swing clearance. Every beam is laser-cut and pre-drilled; no onsite drilling or welding. The sliding purlin clamp system allows ±50mm module adjustment to compensate for concrete foundation deviations. Two workers with a boom truck can typically complete it. Each shipment includes full bolt kits, leveling shims, module rails for 30/35/40mm frames, and tilt options of 5°, 10°, or 15°. We back every project with PE-stamped structural calculations, foundation drawings, and step-by-step installation videos. Worldwide shipping.

Why Single Post? 

Unlike bulky double-post designs that eat up parking width, our single post sits neatly between two parking bays. The cantilever arm extends up to 5.5 meters without a front leg, so drivers can swing doors open fully—no more dented doors or tight squeezes. For site planners, this means you fit more panels and more cars in the same footprint.

Steel That Works Hard. 

We use Q355B high-strength structural steel with a 275 g/m² hot-dip galvanized coating. This gives you 25+ years of corrosion protection in coastal or high-humidity environments. Every weld is inspected with magnetic particle testing—we don't rely on visual checks alone.

Wind & Snow – We Did the Math. 

Wind load: up to 35-40 m/s—tested in a boundary layer wind tunnel. 

Snow load: up to 0.6-0.75 kN/m². The base plate uses anchor bolts with shear keys, so the post stays put even in typhoon-prone regions.

Installation—No Headaches. 

All beams come with laser-cut holes—no drilling on site. The purlin connections use a sliding clamp system that allows ±50mm module adjustment, so you can correct for concrete foundation deviations without re-fabricating parts. A two-man crew can typically set with a boom truck.

EV-Ready Design 

We've reserved a dedicated cable tray under the beam for DC charging cables and inverters. The gutter system integrates with standard drain pipes, so rainwater doesn't pool on your modules.

Features

1. Carport solar systems have almost no geographical restrictions, are easy to install, and are very flexible and convenient to use. 

2. Excellent heat absorption properties make it cooler than ordinary membrane structure carports, solving the problem of high temperatures inside cars during summer. 

3. Low cost, full utilization of existing sites, no need to occupy additional land resources. 

4. Utilizing solar energy to generate clean, green electricity for charging electric vehicles and new energy vehicles, supplying electricity to businesses, and even earning money by connecting to the grid. 

This is a no-nonsense carport for developers who want a 30-year car parking lot. We ship worldwide with project-specific engineering stamped by a PE. Drawings and BOM included.

FAQ

Q1. What is the standard column spacing of the single-post carport? Can it be customized? 

A: The standard column spacing is 5.0m to 6.0m. It can be customized according to project topography and parking space dimensions and adjusted per client requirements.

Q2. What material is used for the main structure? How is anti-corrosion treated? 

A: The main structure is made of high-strength steel (Q235B/Q355B) with hot-dip galvanized surface treatment (65-80 μm coating thickness), ensuring over 25 years of corrosion resistance outdoors. Aluminum alloy options are also available upon request.

Q3. What are the maximum wind and snow loads this carport can withstand? 

A: The system is designed for wind loads up to 35-40 m/s and snow loads up to 0.75 KN/m², making it suitable for coastal, inland blizzard, and other extreme climate areas.

Q4. Can the module tilt angle be adjusted? What is the range? 

A: Yes, the tilt angle is customizable from 0° to 15°. We can optimize the angle based on the project latitude and energy yield requirements.

Q5. What type of foundation is required? Is on-site welding necessary? 

A: Common foundations include concrete foundations or chemical anchoring. Most parts are pre-assembled in the factory; only bolting is needed on site—no cutting or welding, ensuring fast installation and quality control.
