Electro-galvanized rectangular tubes of 40x80x1.5mm are available in fixed lengths for Q195 greenhouses/scaffolding

Crafted from Q195 steel, these rectangular tubes possess a unique set of properties that make them well-suited for greenhouses and scaffolding. Q195 is a low-carbon steel grade known for its good plasticity and formability, which allows for easy fabrication and shaping during the manufacturing process. This characteristic ensures that the 40x80x1.5mm rectangular tubes can be precisely cut, bent, and assembled to fit the specific requirements of different greenhouse and scaffolding designs. Despite being a low-carbon steel, Q195 still provides sufficient strength to support the loads and stresses encountered in these applications. In greenhouses, it can bear the weight of the roofing materials, plants, and the impact of wind and snow, while in scaffolding, it offers reliable support for workers and equipment during construction and maintenance tasks.
