Build Your Specification
Build a complete hollow-section specification
Select section type, material, grade, standard and size. The builder assembles a full specification you can copy, review, or submit for quotation.
The builder is a first-pass guide, not a catalogue. Noor Deira Steel reviews every specification by hand and confirms grade availability, section properties and delivery. Pricing is always on request — request a quotation to receive a confirmed offer.
Grades, Standards, Sizes & Tolerances
Dimensions and section properties you can design against
Section size, wall thickness and section properties tie directly to the governing standard. The reference below helps you frame a specification before Noor Deira Steel confirms the exact grade and wall against your order.

| 150 × 100 mm | 4.0 – 10.0 mm | Beams and portal frame members |
| 200 × 200 mm | 6.0 – 16.0 mm | Heavy columns and bridge elements |
| 250 × 150 mm | 6.0 – 12.5 mm | Long-span beams and trusses |

Procurement Insight
Why hollow beat solid at the same weight
A common procurement error is to compare sections on mass per metre alone. For a given weight, a hollow section spreads material away from the neutral axis, so it carries more bending load than an equivalent solid bar. That is why an SHS or RHS can replace a heavier solid member in a column or beam — the stiffness benefit comes from geometry, not extra metal.
| Section | Outer dims | Wall | Unit weight |
|---|---|---|---|
| SHS | 100 × 100 mm | 5.0 mm | ≈ 14.9 kg/m |
| RHS | 150 × 100 mm | 6.0 mm | ≈ 22.9 kg/m |
| CHS | 114.3 mm OD | 5.0 mm | ≈ 13.5 kg/m |
Unit weight for a rectangular hollow section ≈ 0.00785 × (2 × t × (w + h) − 4 × t²), with dimensions in millimetres (for CHS, weight ≈ 0.02466 × t × (D − t)). Because section material sits at the extreme fibres, hollow profiles deliver a high strength-to-weight ratio — which is why they are the default for columns and efficient trusses.

Frequently Asked Questions
Hollow sections, answered for buyers
Direct answers to the questions procurement teams ask most about hollow sections.
What hollow sections can Noor Deira Steel supply?
Square (SHS), rectangular (RHS), circular (CHS), cold-formed and oval hollow sections in galvanized, carbon and mild steel. Availability is confirmed against your specification, not from a standing catalogue.
What is the difference between SHS, RHS and CHS?
SHS has equal sides, RHS has unequal sides, and CHS is circular. SHS offers high torsional stiffness; RHS suits beams and asymmetric loads; CHS provides uniform radial stiffness for columns and architectural work.
What is the difference between cold-formed and hot-finished hollow sections?
Cold-formed sections are rolled and welded from strip or coil to tight tolerance (EN 10219, ASTM A500); hot-finished sections are formed at elevated temperature (EN 10210). The choice depends on tolerance needs and design code.
Which grade do I specify for structural hollow sections?
ASTM A500 Gr. B/C and ASTM A1085 are common in North-American design; EN 10219 S355J2H and EN 10210 are common in European and Gulf design; JIS G3466 STKR serves Japanese-standard projects. Confirm the governing code and grade together.
What does A500 Grade B vs Grade C mean?
Grade C has a higher specified minimum yield strength than Grade B. ASTM A500 cold-formed sections; the grade choice is governed by the structural design and its yield requirement.
What information do I need to request a hollow section quotation?
Section type, material, grade, standard, width, height, wall thickness, length, quantity, destination and Incoterm. The Specification Builder collects these fields and hands them to our commercial department.
Does Noor Deira Steel supply hollow sections across the GCC?
Yes — Noor Deira Steel coordinates hollow section supply to the UAE, Saudi Arabia, Qatar, Oman, Kuwait and Bahrain, with Incoterms, bundling and destination documents agreed per order. Lead time is confirmed at quotation stage.
