Steel girders & sections — bulk supply in Lahore

Steel sections are the structural shapes used for steel roofs, sheds, mezzanines, staircases, canopies, frames and supports in retrofitting. In Lahore the word "garder" often means an I-section or beam used in a roof or floor, and T-iron is still seen in older girder-and-tile roofs.

Types and specifications

Sections are described by their dimensions (depth, flange width, thickness) and often by weight per metre. Your structural engineer's drawings should list the exact section for each member.

What each is used for

• Roofs and sheds: girders or trusses with channel or Z purlins.
• Mezzanines and extensions: I-beams or H-sections with steel decking or slabs.
• Retrofitting: steel beams and columns to support weak members, plates bonded or bolted to concrete.
• Stairs and canopies: channels, angles and hollow sections.

Quality checks on delivery

1. Dimensions. Measure depth, flange width and web/flange thickness against the order.
2. Weight. Weigh a full length and compare with the weight per metre stated by the supplier or on the drawing. Under-weight sections are thinner than ordered.
3. Length. Check lengths against the cutting list.
4. Straightness. Sight along the length for bends or twists.
5. Surface. Check for heavy rust, pitting, laminations or cracks.
6. Mill certificate. Ask for it for structural members.
7. Second-hand steel. If offered used sections, check condition carefully and ask your engineer if they are acceptable.

How much you need

Your engineer or steel fabricator prepares a member list with section type, size and length. Total length by section, multiply by weight per metre and add cutting allowance. Steel fabricators often buy steel themselves; decide early whether you buy the steel or the fabricator does.

Bulk-buying tips

• Get quotes per kg or per ton, delivered, with taxes stated.
• Ask whether the supplier can cut to length to reduce transport and waste.
• Arrange a crane or enough workers for unloading long, heavy pieces.
• Store on timber bearers, off the ground, and cover to slow rust.
• Paint with primer early if steel will sit on site for long.
• Keep invoices and certificates for the project file.

What affects the price

• Section type and size. Heavier and less common sections can carry higher rates.
• Steel market rates for the day.
• New vs used steel.
• Cutting, drilling and fabrication.
• Delivery length. Long sections need suitable transport.
• Order size.
• Taxes and invoicing.

FAQs

What is the garder rate in Lahore? Girders and sections are priced by weight and section type, and rates change with the steel market. Ask suppliers for a written per-kg or per-ton quote for your exact sections.

Can I use second-hand girders? Sometimes, for non-critical work, if your engineer checks size and condition. For main structural members, ask your engineer first.

What is the difference between a girder and a channel? A girder (I-beam) has two flanges joined by a web and is used as a main beam. A channel has flanges on one side and is used for purlins, frames and lighter beams.

Do steel sections need painting? Yes. Exposed steel rusts, so it is usually primed and painted, or galvanised for outdoor use.
