Spring steel is typically produced from high-carbon steel, offering impressive tensile strength, wear resistance, and the ability to maintain shape after deformation. The most common grades utilized for spring steel coils include ASTM A228, A313, and A421, each having distinct qualities suited for specific applications. For instance, ASTM A228 is often used for music wire due to its excellent strength and surface finish, while A313 is preferred for general-purpose springs.

Coil springs are susceptible to rust and other environmental factors, which can lead to premature failure. To enhance durability, they are often coated with powder, epoxy, or polyester, and some are electroplated with zinc or nickel for added protection.

وظیفه اصلی بندهای تای بریک، تأمین پیوستگی و انسجام دیوارهای آجری است. این بندها به جلوگیری از صاف شدن دیوارها و همچنین کاهش ریسک ایجاد ترک‌های ناشی از تنش‌های مختلف کمک می‌کنند. به علاوه، بندهای تای هم به کنترل حرارت و رطوبت کمک می‌کنند و در نتیجه از بروز مشکلات ناشی از تغییرات جوی در دیوارهای آجری جلوگیری می‌کنند.
