Here is a rewritten version of the text in English: **Armored Casing Production** Our company produces armored casings made from steel rods with various degrees of rust-resistance. The main marks of steel used are St3, 55G2S, 26G2S, 22G2R, 22H2G2T, 22H2G2AYu, and 20H2G2SR. Upon request from the customer, other marks of steel can be used if their properties do not reduce the physical-mechanical characteristics of the armored casings. **Strength of Joint Connections** The reliability and durability of reinforced concrete structures depend on the strength of connections between elements of armored casings. Three methods are used to connect steel rods: 1. Welding: Our company uses welding under flux according to GOST 8713-79. 2. Locking: Metal rods are connected without welding. The rods are laid crosswise and secured with wire according to GOST 282-74. 3. Mechanical connection: Rods are connected using pressed or threaded bushings according to GOST 4278-2017. **Table 2: Strength of Welded Flat Armored Casings** | Class of Steel Rods | Resistance to Breakage, H/mm | | --- | --- | | A240 | 450 | | A300 | 500 | | A400 | 560 | | B500S | 710 | | A600S | 820 | | A800 | 910 | | A1000 | 1000 | **Quality Control** Each batch of armored casings undergoes mandatory quality control. The quality and reliability of connections are assessed by testing, including resistance to stretching, bending, cutting, and separation forces. The types and modes of testing are determined in agreement with the customer. **Delivery and Storage** The delivery of flat armored casings should prevent deformation and mechanical damage to metal products. It is recommended to transport them horizontally and secured in bundles. Transportation by any type of ground transportation is allowed if the rules for transporting on this type of transportation are followed. **Ordering Procedure** To place an order for the production and delivery of armored casings, please call our phone number listed on our website. Our manager will provide details on payment terms and delivery options, offer discounts, and answer any questions you may have.
