How to Download a PDF Guide for BS 8666 Shape Codes
BS 8666 is the British Standard for scheduling, dimensioning, bending and cutting of steel reinforcement for concrete. It specifies the requirements for the shape codes, notation, dimensions and tolerances of steel bars used in construction projects. The latest version of BS 8666 is BS 8666:2020, which updates the standard more closely with BS EN 1992-1-1 Eurocode 2.

Why do you need to know the BS 8666 shape codes?
The BS 8666 shape codes are essential for ensuring the correct bending and cutting of steel reinforcement bars for concrete structures. They help to avoid errors, wastage and delays in the construction process. They also ensure that the reinforcement conforms to the design specifications and meets the structural performance requirements.
How do you use the BS 8666 shape codes?
The BS 8666 shape codes are used to describe the geometry and dimensions of each steel bar in a reinforcement schedule. A reinforcement schedule is a table that lists the details of each bar, such as the type, grade, size, shape code, length, quantity and location. The reinforcement schedule is usually prepared by the structural engineer or the detailer, and is used by the fabricator and the installer to produce and place the reinforcement correctly.
The BS 8666 shape codes consist of two digits, followed by a series of letters and numbers that indicate the dimensions of each bend or straight section of the bar. For example, shape code 11 means a bar with one bend at an angle between 135Â and 180Â. The dimensions are given as A and B, where A is the length of the straight section before the bend, and B is the length of the straight section after the bend. The radius of the bend is given by r, and the diameter of the bar is given by d. The total length of the bar is calculated as L = A + B - 0.5r - d.
