Bar bending schedule or bar chart representation scheme is full of cut and bend bars as required by strengthening retail design. It helps in determining adequate quantities of material, strength and cost estimates.

Bar bending schedule is used as a guide in the placement of various structural elements such as footings, beams, columns, beams, pillars, walls, etc. to casting.

Examples include the curvature of the hooks, stirrups and bent slats, a meeting point for the top and bottom bars, anchor bend, double bars in sheets, belts, U, and turn the longitudinal re-bars. histogram scheme requires a thorough structural analysis to improve security and stability of the concrete structure.

In the UK, BS 8666:2000 standard specifies requirements for bar bending schedule, sizing and cutting of steel reinforcement. Gradually replaced old BS8666 BS 4466 which is still used in some contracts. The discrepancy in the codes of form between these standards is important, and sometimes lead to contradiction. Therefore, it is essential that used standard is clearly on the schedule.

The bar bending schedule is used to communicate requirements for cutting and folding of detail the manufacturer. The schedule includes specialized notes to describe various reinforcing materials in the market – including the different grades of stainless steel standard (BS6744) carbon steel (BS4449) and special steels.

Although the process of cutting and bending of reinforcement is relatively complex, the manufacturer is well equipped to do the job within a defined set of criteria for quality management. The accuracy of cutting and bending activities is essential to ensure proper fit on the site and to facilitate length required anchorage lengths back and cover.

In recent times the basic practices of cutting and bending have changed considerably due the increasing use of a computer control, automation systems and IT. A recent development is the strengthening of carpets, which consists of a series of reinforcing bars welded to a lean steel band. It can be rolled up like a carpet and is suitable for the reinforcement of many types of stones. It is noted that the system of carpet can offer savings of up to 30-40% material and 80-90% in the determination of costs!
