Complete PEB building kits

What a complete PEB kit includes

A complete pre-engineered building kit is a single, coordinated supply of every component needed to close in a steel building: the primary framing, the secondary framing, roof and wall cladding, accessories and the bolts that join them. World Steel designs the whole building as one system, so the loads, connection details, sheeting spans and trims are checked together rather than bought from several suppliers and reconciled on site. The kit is the core of the PEB buildings range and the most common form of pre-engineered building export from the Tay Ninh plant.

The standard scope of supply is:

• Primary frames: tapered or prismatic built-up columns and rafters, endwall columns and rafters, base plates, end plates, splice plates and stiffeners.
• Secondary framing: cold-formed Z and C purlins and girts, eave struts, flange braces, rod or cable bracing, portal bracing and sag rods.
• Roof and wall cladding: metallic-coated or pre-painted trapezoidal or standing seam sheets, with matching fasteners, closures and sealant.
• Accessories as specified: gutters and downspouts, trims and flashings, skylights, ridge ventilators, louvers, framed openings, doors and canopies.
• Structural bolts (high-strength and machine bolts), anchor bolts with nuts and washers, and cladding screws.
• Documentation: anchor bolt plan, erection drawings, design calculations, material certificates and packing lists.

Options and variants

The kit adapts to most single-storey building types. Frame form follows the span and use: clear-span frames for unobstructed floors, multi-span frames with interior columns for very wide buildings, single-slope frames, lean-to extensions, crane buildings and mezzanine buildings. Options can be added without changing the supply model:

• Insulation: blanket insulation under the sheet or insulated sandwich panels.
• Roof system: through-fastened trapezoidal sheet or a standing seam roof for low slopes and long runs.
• Crane runway beams and brackets, mezzanine floors, canopies, fascias and parapets.
• Finish upgrades: hot-dip galvanized framing, higher-durability paint systems to ISO 12944, or higher-coating-mass sheet for coastal sites.

Foundations, concrete slabs, masonry, building services and site works are normally by others; World Steel provides the anchor bolt plan and base reactions for the foundation designer.

Materials, finishes and documentation

Built-up members are welded from structural plate such as ASTM A572 Grade 50, AS/NZS 3678 Grade 350 or EN 10025-2 S355, selected to suit the design code of the destination. Purlins and girts are roll-formed from galvanized high-strength coil (for example ASTM A653 SS Grade 55, AS 1397 G450 Z275 or EN 10346 S350GD+Z275). Cladding is aluminium-zinc coated or pre-painted sheet. Primary steel is shot blasted to ISO 8501-1 Sa 2½ and primed or painted to a specified system.

Each part is piece-marked to the erection drawings, and the IFC model lets the client check the building in any BIM viewer before shipment.

Compliance by market

The same building is designed and fabricated to a different rule set in each market. The table states what WSC holds and what must be arranged per project; see market compliance and certification for detail.

Sundries, special buyouts and items by others

A clear split between what is in the kit, what is bought out for the project and what is supplied by others avoids gaps on site. World Steel states this split in every quotation.

See sundries: sealants, closures, rivets and tapes for the small items that complete the envelope.

Packing and how to request a quotation

Kits are packed for sea freight in 40 ft high-cube containers or on flat racks for long rafters, with sheets bundled on timber skids, bolts in labelled boxes and every bundle listed on the packing list (see packing and shipping).

A quotation can be prepared quickly when the enquiry states the project location and the code to be used. Please send:

1. Site location, building use and importance level.
2. Width, length, eave height, roof slope and bay spacing.
3. Applicable code and any specified loads (wind speed, snow, seismic, collateral).
4. Openings, cranes, mezzanines and accessories required.
5. Required finish, insulation and delivery terms (FOB, CIF or DAP).

World Steel returns a priced scope with a clear inclusions and exclusions list, the design basis assumed and a typical lead time. Enquiries go through the export supply team in Ho Chi Minh City.
