Product Name
Medium Steel Angle (Medium-Duty L-Section / Medium Angle Steel)
Introduction
Medium Steel Angles are equal- or unequal-leg L-shaped structural sections sized between light-duty shop angles and heavy bridge/industrial angles. They offer a practical balance of strength, stiffness and economy for structural framing, bracing, machinery supports and medium-duty load-bearing connections. Supplied as rolled or fabricated plate angles, they are easy to bolt, weld or cut-to-length and are commonly used in building, plant, transport and agricultural structures.
Typical Materials & Grades
Carbon / structural steels: S235 / Q235, S275, S355 (EN); A36, A572 Gr.50 (ASTM).
HSLA options: S420 / S460 where reduced weight or higher yield is required.
Corrosion-resistant options: weathering steel (Corten), stainless (304/316) or hot-dip galvanized finishes.
Supply documentation: Mill Test Certificates (MTC) and heat-number traceability available.
Typical Geometry & Ranges
Leg lengths (a × b): commonly 50 mm – 200 mm (equal or unequal).
Thickness (t): 6 mm – 30 mm (medium-duty range).
Lengths: standard stock lengths 6 m / 12 m; cut-to-length, mitred or spliced to suit.
Mass per metre (approx): mass (kg/m) ≈ (a + b − t) × t × 0.00785
Example: 100 × 100 × 10 mm → (100+100−10)×10×0.00785 ≈ 18.77 kg/m
Key Features & Advantages
Good load capacity: large enough leg areas to support moderate bending and axial loads without excessive weight.
Versatile connection faces: flat legs simplify bolting, welding and gusset attachments.
Easily fabricated: cut, drilled, notched and coped quickly in shop or on site.
Cost-effective: often the most economical solution for medium-strength bracing and framing.
Durable finishes: readily hot-dip galvanized or painted for extended service life outdoors.
Typical Applications
Secondary framing, bracing and diagonal members in buildings and plant structures.
Machine bases, conveyor supports and medium-duty equipment mounts.
Trailer/chassis reinforcement, agricultural implement brackets and hitch points.
Stair stringers, handrail supports and platform framing.
Splice plates, gusset plates and retrofit repair angles in structural repairs.
Fabrication & Value-Added Services
Cutting & coping: CNC plasma/laser cutting for accurate copes and splice faces.
Pre-drilling / punching: match-drilled bolt patterns to reduce site work.
Welding & assemblies: welded gussets, doublers and pre-assembled corner brackets.
Surface treatment: shot-blast + primer, hot-dip galvanize, epoxy/PU coatings or duplex systems.
Pre-assembly & kits: numbered erection packs with splice plates, bolts and installation notes.
Quality Assurance & Testing
Material certification: MTCs with chemical & mechanical test results.
Dimensional checks: leg length, thickness, squareness and straightness verification.
Welding control & NDT: WPS/PQR governed welding; MT/UT available for critical joints.
Coating inspection: galvanize mass, paint film thickness and adhesion testing per project spec.
Packaging, Transport & Delivery
Bundling: strapped bundles with timber or polymer spacers to avoid marking.
Protection: end/corner guards, VCI/oil for export or long storage.
Marking: size, part ID, heat number and orientation stamped or tagged.
Lead times: stock sizes short (days–2 weeks); pre-drilled, coated or fabricated orders typically 2–8 weeks depending on scope.
How to Order / What We Need
Please provide:
Angle size (a × b × t) and length(s) × quantity.
Material grade and finish (black / galvanized / painted / stainless).
Any value-added items required (holes, slots, doublers, weld-on brackets).
Tolerance/straightness needs for precision assemblies.
Delivery constraints (single-piece transport lengths) and lead time target.
Any testing or certification needs (MTC, NDT).
Why Choose Our Medium Steel Angles?
We supply medium-duty angles optimized for real-world fabrication and erection: stocked core sizes for fast delivery, custom-fabricated larger sizes, and shop-ready value-adds (drilling, welding, coatings) to reduce site labour and speed installation. Send your size list or a typical connection detail and we'll propose specific sizes, weights (kg/m), and finishing/assembly options.
