Black square\/rectangular pipes feature original hot-rolled black oxide surface without anti-corrosion treatment, with high structural strength and excellent weldability. Galvanized square\/rectangular pipes are processed with hot-dip galvanizing technology on the basis of black pipes, forming a dense zinc-iron alloy layer on the surface. Both products have uniform wall thickness, stable dimensional accuracy and strong structura<\/p>\n<p>l stability, widely applicable in building structures, engineering construction, decoration and mechanical manufacturing fields.<\/p>\n<\/div>\n<div id='gallery-1' class='gallery galleryid-5637 gallery-columns-3 gallery-size-full'><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon
