Commercial 40x40' tent frame fits our west-coast frame tents. Its rigid construction allows the tent to set up without requiring any center pole. Therefore, it expands the tent's interior space and offers an obstruction-free setup for the event. This frame also features an expandable system. You can make several sizes of larger frames with some additional parts and fittings by adding to the existing structure. The heavy-duty 2-inch diameter anodized aluminum framework is lightweight than the galvanized steel, yet it offers more durability and ease of set up than traditional galvanized steel. Rust-resistant and corrosion-resistant aluminum tent frame ensure the tent to last for many years to come.
