Rebar & Reinforcement Steel
Reinforcing bar (rebar) is deformed steel bar embedded in concrete to carry the tensile load concrete alone cannot, the standard reinforcement for every cast-in-place and precast concrete element on a project. NLS sources deformed rebar to ASTM A615 and BS 4449, in Grade 60 (A615) and B500B (BS 4449) equivalents, sizes 8mm to 32mm, cut and bent to a bar bending schedule.
Concrete is strong in compression and weak in tension, which is why almost no structural concrete element gets built without steel reinforcement inside it. Reinforcing bar, deformed with ribs along its length so it grips the surrounding concrete rather than pulling free, carries the tensile and shear stress the concrete matrix can't, working with the concrete as one composite material rather than as a separate part.
NLS sources deformed rebar to two main standards. ASTM A615 covers deformed and plain carbon steel bars for concrete reinforcement, most commonly supplied as Grade 60 (60,000 psi yield strength), the standard grade on projects following American reinforcement practice. BS 4449 covers reinforcing steel to British and European convention, most commonly B500B, a weldable, high-ductility grade widely used across the Gulf. Sizes run from 8mm up to 32mm diameter, supplied as straight lengths or cut and bent to a bar bending schedule (BBS), the drawing that specifies each bar's shape, length, and bend dimensions for a given pour.
On Saudi projects, rebar reinforces foundations, footings, slabs, columns, beams, and every other cast concrete element on a building, from villa footings up to major structural slabs and precast elements. The bar size, spacing, and cover are set by the structural design, and getting the bar bending schedule right before ordering avoids the common site problem of cut bars that don't match the actual formwork.
NLS quotes rebar against diameter, grade, and quantity (by weight or by a bar bending schedule), and returns a priced quote in USD. Straight, uncut Grade 60 or B500B bar in standard diameters typically sources fastest, while bent-to-schedule orders and larger diameters carry a mill or fabrication lead time confirmed at quote stage.

Frequently Asked Questions
What's the difference between ASTM A615 and BS 4449 rebar?+
They're reinforcing bar standards from different design traditions. A615 Grade 60 is the American reference, sized and graded to US practice, while BS 4449 B500B follows British/European convention. A project's structural design code determines which standard applies.
Can NLS supply rebar cut and bent to a bar bending schedule?+
Yes. Rebar can be quoted as straight mill lengths or cut and bent to a bar bending schedule (BBS), the standard practice for foundation and slab reinforcement where each bar's shape needs to be fixed before it reaches site.
What information does NLS need to quote rebar accurately?+
Bar diameter, grade or standard, and total quantity, ideally as a bar bending schedule with weight and shape breakdown by bar mark, since a schedule prices more accurately than a lump tonnage figure alone.
