Q:How are steel coils used in the production of storage racks and shelving?
Storage racks and shelving heavily rely on steel coils during their manufacturing process. These coils, typically made from high-quality steel, are rolled into long, continuous strips. The steel coils undergo further processing to transform them into sheets or strips, which are then used to construct the frames, shelves, and other structural components of storage racks and shelving systems. Initially, the steel coils go through a series of machines to unwind and flatten them, ensuring uniform thickness and width. This step enables manufacturers to obtain steel sheets or strips with consistent dimensions, which are vital for producing storage racks and shelving that meet specific design specifications and structural requirements. After flattening and cutting the steel coils into desired sizes, they undergo additional processing to incorporate necessary features and characteristics. This may involve bending, punching, or welding the steel to create desired shapes, such as uprights, beams, or brackets for the storage racks and shelving. These components are then assembled to form the framework of the storage system. The durability and strength of steel make it an ideal material for storage racks and shelving. Steel coils provide the essential structural integrity and load-bearing capacity needed to support heavy items and endure regular use. Additionally, steel is resistant to corrosion, ensuring the longevity and reliability of storage racks and shelving systems. Furthermore, steel coils can be coated or galvanized to enhance their resistance to rust and corrosion. This protective layer helps maintain the visual appeal and structural integrity of the storage racks and shelving, particularly in environments with high humidity or exposure to moisture. In conclusion, steel coils play a crucial role in the production of storage racks and shelving. They serve as the raw material for fabricating various components, guaranteeing the strength, durability, and load-bearing capacity necessary for these storage systems. The versatility and adaptability of steel allow manufacturers to create storage racks and shelving that meet specific design requirements and provide long-lasting storage solutions for a wide range of applications.

Q:Hi, I live in the Boston area and I'm trying to find a steel suppler that can provide mild steel for hobby welding. I can go through my job, but we only put in orders every couple of months so it's not very convenient. Also, the few suppliers I've found only sell in bulk. So if anyone knows where I can angle irons, flat bars, sheets, etc... by the piece it would greatly appreciated. Thanks
They will sell any quantity of metal and even cut it to size - my experience has been that their prices are not wildly out of line for single pieces of full length stock compared to buying singles where you have to buy a minimum. They also may have sizes that ordinary places consider odd. I was looking for 5/8 square 16 gauge and was told it would have to be shipped in from Houston (to Dallas) by my nearest supplier and found it in stock at MetalSM. But check if you get something odd - the 5/8 cost more than 3/4 at both places and MetalSM actually gave me 3/4 but took it back even though I had cut it. Also check the regular steel suppliers in your area as well as retail welders metal supply places.
