Metal fittings for structural pipes are manufactured by HULK Metal. In order to produce structural pipe fittings faster, we have all the molds (can suit tubes of sizes A, B, C, D, E, T) and an advanced casting factory. To make the product more beautiful, we can sandblast, spray, galvanize, and apply other surface treatments.
