Double Column Solar Carport: Portal‑Frame ZAM Steel Solution for Commercial Parking
More businesses, industrial parks and public parking lots are turning to solar carports to make full use of open parking space, generate clean electricity and provide shade and rain protection for vehicles. Among multiple structural options on the market, the double‑column solar carport, also known as portal‑frame solar carport, stands out for its superior stability, large‑span capability and flexible custom options.
Unlike single‑column or cantilever solar carport models that rely on one‑side support, a double‑column solar carport adopts a portal‑frame design with vertical support columns on both sides of each bay. Two columns work together to hold up the solar canopy structures. This mechanical layout distributes wind load, snow load and solar module weight evenly onto two support points, greatly improving overall structural safety.
