Anchor Bolts
Anchor bolts fix a steel base plate, equipment skid, or foundation-mounted item to concrete, transferring uplift, shear, and overturning load from the steel into the foundation. NLS sources anchor bolts to ASTM F1554, grades 36, 55, and 105, as L-bolts, J-bolts, or straight headed bolts, cast-in during the concrete pour or set with post-installed adhesive or mechanical anchors.
An anchor bolt is the connection between a steel structure and its concrete foundation, embedded in the concrete on one end and threaded to take a nut and base plate on the other. Everything the column or equipment above transfers down, dead load, wind uplift, seismic shear, overturning moment on a tall or cantilevered structure, passes through that bolt into the concrete, which makes anchor bolt grade and embedment depth a foundation design item, not a hardware afterthought.
NLS sources anchor bolts to ASTM F1554, the standard structural anchor bolt specification, in three grades: Grade 36 (the most common, lower-strength grade for standard column base plates), Grade 55, and Grade 105 (higher-strength, used where a heavier structure or higher uplift load needs more capacity per bolt). Configurations include L-bolts and J-bolts (bent at one end for embedment anchorage), straight headed anchor bolts (a forged or upset head instead of a bend), and hex head anchor bolts. NLS supplies both cast-in bolts, set in a template before the concrete pour, and post-installed anchors, chemical (adhesive) or mechanical expansion type, for fixing to existing, already-cured concrete.
On Saudi projects, anchor bolts fix structural steel column base plates, equipment and skid foundations, light pole and mast bases, and any steel-to-concrete connection carrying uplift or overturning load. Cast-in bolts need a template and correct positioning before the pour, so anchor bolt supply usually has to land on site ahead of the concrete schedule, not after.
NLS quotes anchor bolts against diameter, length, grade, and bend configuration (L, J, straight, or headed), and returns a priced quote in USD. Standard Grade 36 bolts in common diameters typically source fastest, while Grade 105 high-strength anchors or long embedment lengths more often carry a manufacturer-confirmed lead time.

Frequently Asked Questions
What's the difference between ASTM F1554 Grade 36, 55, and 105 anchor bolts?+
They're strength grades under the same specification. Grade 36 is the standard-strength, most common grade for typical column base plates. Grade 55 and Grade 105 step up in tensile strength for heavier structures or higher uplift and overturning loads, specified by the foundation design.
Can NLS supply anchor bolts for concrete that's already cured?+
Yes. Post-installed anchors, chemical (adhesive) or mechanical expansion type, are used for anchoring into existing, already-cured concrete where a cast-in bolt wasn't set at pour time.
Why does anchor bolt supply need to be scheduled ahead of the concrete pour?+
Cast-in bolts are set in a template and positioned in the formwork before concrete is poured, so they need to be on site and correctly located ahead of the pour date, not ordered as an afterthought once the foundation is already cast.
Who supplies Anchor Bolts in Saudi Arabia?+

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.
Welded Wire Mesh
Welded wire mesh (welded wire fabric) is a grid of steel wires welded at each intersection, used as light, uniform concrete reinforcement for slabs and pavements where a mesh gives faster crack control than individually placed bars. NLS sources welded wire fabric to ASTM A185 and BS 4483, in standard sheet or roll format, wire gauge and spacing matched to the slab design.
Angles, Channels & Flats
Angles (L-shape), channels (C-shape), and flat bars are the standard hot-rolled sections behind secondary steel: bracing, brackets, supports, and light framing, rather than primary beams and columns. NLS sources these sections to EN 10025-2 and ASTM A36, equal and unequal angles, standard channel sizes, and flat bar in a range of widths and thicknesses, supplied cut to length or as fabricated brackets.
Chequered Plates
Chequered plate is steel plate with a raised diamond or lentil pattern rolled into its surface, giving slip resistance on foot traffic areas without a separate coating or coarse finish. NLS sources chequered plate to ASTM A786, in standard base thicknesses from 3mm to 12mm, mild steel and hot-dip galvanized, sized to stair treads, platform flooring, and ramp panels.
Steel Gratings
Steel gratings are welded or pressure-locked open-mesh steel panels used for walkways, platforms, drainage covers, and trench covers where drainage and light transmission matter as much as load capacity. NLS sources welded and swage-locked steel grating in mild steel, galvanized, and stainless steel, standard bearing bar depths from 25mm to 50mm, to BS 4592 and ANSI/NAAMM MBG 531, sized to project loading tables.
Structural Fasteners
Structural fasteners, high-strength bolts, nuts, washers, and anchor bolts, hold steel connections together under design load, sized and graded to the connection's calculated capacity rather than picked off a generic hardware shelf. NLS sources structural bolt assemblies to ASTM A325/A490 and ISO 4014/4017, hot-dip galvanized and plain finish, from M12 to M36, for structural steel and foundation connections on Saudi projects.
