Steel & Structural Materials

NLS supplies steel gratings and structural fasteners for Saudi industrial and infrastructure projects, sourced in galvanized and stainless steel across standard load classes and bolt grades from 4.6 up to 8.8 and A193/A194 for higher-duty applications. Quotes run in USD against a structural drawing or BOQ, with delivery timed to a project's steelwork erection sequence.

What NLS supplies in steel and structural materials

Structural steel packages on Saudi sites split into two categories that show up on almost every BOQ: steel grating for walkways, platforms and drainage covers, and structural fasteners, the bolts, nuts, washers and anchor sets that hold the steelwork together. NLS sources both, with grating available in welded and press-locked bar formats, mesh sizes typically 30x3mm to 40x5mm bearing bar, and galvanized or stainless steel finish depending on the corrosivity of the environment (coastal Jubail and Yanbu sites usually specify hot-dip galvanized at minimum, sometimes 316 stainless in process areas).

Fasteners cover standard grade 4.6 and 8.8 bolts for general structural connections up through A193 B7 studs and A194 2H nuts for higher-temperature or higher-load flanged joints, plus anchor bolts and chemical anchor sets for baseplate connections. NLS quotes fastener packages by drawing takeoff rather than a per-piece price list, since a single steel BOQ can run into thousands of pieces across a dozen different grades and sizes.

How sourcing and pricing work

Steel and fastener pricing tracks raw material cost, which moves with international steel and zinc prices, so NLS quotes in USD with a validity window, usually two to three weeks, stated on the RFQ response. Lead time for standard galvanized grating panels in common sizes runs three to six weeks, longer for stainless steel or custom panel dimensions. Fastener packages ship faster when the grades are common (4.6, 8.8) and stocked, typically two to four weeks, extending to six to ten weeks for A193/A194 high-temperature grades or large anchor bolt diameters that need mill certification.

Why project buyers use NLS for steel and structural materials

A steelwork package that's short even a handful of the right-grade bolts stalls an erection crew on site, so NLS builds the fastener BOQ against the same drawing set as the grating and structural items, checking grade and quantity consistency before the quote goes out rather than after delivery. NLS is a Saudi-registered company based in Riyadh, prices the steel and fastener hardware in USD and handles local delivery in SAR, and mill certificates and material test reports come with the shipment as standard rather than as a chased-down afterthought once the steel is already on a barge.

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.

Manual Welded Industrial Gratings

NLS Industries supplies manual welded industrial gratings essential for secure walkways, platforms, and trench covers in Saudi Arabia's demanding projects. These gratings offer strength and durability for various industrial and infrastructure applications, meeting specific project needs through custom material, size, and finish options.

Steel Beams & Structural Sections

Structural steel beams and sections, I-beams, H-beams, and channel-type sections, form the load-bearing frame of a steel structure, carrying bending and shear loads across a span. NLS sources hot-rolled universal beams, columns, and W-shapes to ASTM A36, EN 10025-2, and BS 4-1, sized against a structural steel drawing rather than a generic beam list.

Steel Plates & Sheets

Steel plate and sheet are flat-rolled steel products used as the base material for fabrication, structural connections, and vessel or tank construction, plate generally 6mm and thicker, sheet thinner and often coil-fed. NLS sources structural and pressure-quality plate to ASTM A283 and A572, and structural steel sheet to EN 10025-2, in mill or cut-to-size format against a fabrication drawing.

Steel Pipes & Tubes

Steel pipe and tube carry fluid or gas under pressure, or serve as structural columns and posts, supplied seamless (extruded from solid billet) or welded (ERW, rolled and seam-welded). NLS sources carbon steel pipe to ASTM A53, line pipe to API 5L, and seamless pipe to ASTM A106 for high-temperature and high-pressure duty, matched to the project's piping or structural spec.

Gratings & Handrail Systems

Grating and handrail systems combine open-mesh steel decking with a guardrail assembly (posts, top rail, mid rail, and toe plate) into one walkway package for elevated platforms, stairs, and access routes. NLS sources galvanized and painted steel handrail assemblies alongside welded grating panels, guardrail loading referenced to BS 6180 and grating to BS 4592, sized as a system against a platform layout.

Fasteners, Bolts & Nuts

Bolts, nuts, washers, and general hardware fasteners cover the commercial and light-structural fixing that runs across every trade on a project, sized and graded for the job rather than engineered to one connection calculation. NLS sources hex bolts and nuts to ISO 898-1 and ISO 898-2 property classes, plus ASTM A325 grade hardware, from M6 to M30, zinc-plated, galvanized, or stainless.

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.

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.
