FAQ

Steel coils are used in the production of storage systems as they are rolled into sheets and then formed into various components such as shelves, frames, and brackets. These components are then assembled to create sturdy and durable storage systems that can hold and organize various items efficiently.
The common methods of packaging steel coils for transportation include strapping, wrapping, and using wooden or steel cradles. Strapping involves securing the coils with metal or polyester bands, while wrapping involves using stretch film or shrink wrap to protect the coils from moisture and damage. Wooden or steel cradles are used to stack and secure multiple coils together, ensuring stability during transportation.
The typical lead time for ordering steel coils can vary depending on factors such as the supplier, quantity required, and current market conditions. However, it is common to expect lead times ranging from a few weeks to a couple of months.
Steel coils are protected against scratches and damage through various methods such as applying protective coatings, using edge protectors, securely packaging them with appropriate materials, and ensuring careful handling during transportation and storage.
so why shouldn't one use a steel cased 223 in an ar15?
Some have said that steel cases (Russian?) will wear out the extractor prematurely, others have said they have shot thousands of rounds of these with no problems.
The main factors that affect the quality of steel coils include the composition and purity of the steel used, the manufacturing process and techniques employed, the level of heat treatment and cooling, the presence of any impurities or defects, and the overall handling and storage conditions.
We all know that when we drop a small steel ball (size 3mm diameter; weight 1.10 grams) and a paper (size 11.7 inches length and 8.3 inches breadth; weight 4.5 grams) from a height. The steel ball will win the race to the ground due to its aerodynamic structure.Now imagine the same steel ball with the same weight converted to the structure similar that of paper. What will be the result? Which object will fall first; steel sheet or paper?
The 2 objects will have the same size and shape. Therefore they will have the same air resistance. So the heavier object (the sheet of paper) will reach the ground first.
Steel coils can be recycled by first removing any non-steel materials attached to them, such as plastic or rubber. The coils are then shredded into smaller pieces and sent to a steel mill, where they are melted down and transformed into new steel products. This process helps conserve natural resources, reduces energy consumption, and minimizes waste.
