3. MD products are made of full materials. What are the advantages of products made from full materials against products made from tubes?

The process of welding includes high heat. The walls of tubes melt under high heat and thus become thinner,consequently, this part is softer and weaker. When the product is used, the weight that we put on it causes a bending near the welded parts. This bending damages the painting and rust is inevitable. The products made of full materials are more solid and do not suffer from these problems.
