Profile: Architectural Engineering & Manufacturing Design Co., Ltd. is a provider of stainless steel welding fabrication. Our welding and fabrication of stainless steel is complicated by the fact that there are several grades of stainless steel like austentic, duplex, martensitic, and ferritic. These can all be welded, but their weld abilities vary considerably. Our austentic grades are the easiest, and can be welded with all the usual electric methods. These grades are also suited to bending, and are used in a huge number of fabricated products.
