Steel Structure Fabrication for Factories and Warehouses
Turn structural intent into components that can be fabricated and erected
PT KWD supports factories, warehouses and ancillary buildings in Indonesia with steel detailing, fabrication, protective coating, logistics and site-erection coordination. Project quotations follow drawings, location and the agreed delivery scope.
01
Coordination from shop drawings to erection
02
Factory fabrication and component numbering
03
For factories, warehouses and supporting structures
Scope and quotation
Define the scope before comparing steel-structure quotations
Steelwork is quoted by project. A price per kilogram or building area alone does not establish the package cost. Separate component supply from site work so quotations cover the same scope.
Send your steel-structure requirements- Project basics
- City, building use, length, width, height, span, floor area and target construction schedule.
- Drawings and loads
- Available design drawings, calculation requirements, connections and load information. A sketch can start the discussion if drawings are incomplete.
- Members and coatings
- Define detailing, fabrication, material grade, member list, connections, corrosion protection and fire-coating requirements.
- Site and delivery scope
- Confirm transport, lifting equipment, erection and inspections separately. State in writing whether foundations, civil works, roof and wall cladding are included.
- Quantity and pricing basis
- Provide estimated tonnage (t) or floor area (m²), noting whether cladding and erection are included. Drawings and the itemized quotation govern.
Drawings can be shared separately during the WhatsApp discussion. Final design and construction conditions require the responsible engineer's approval. This page is not a structural design document or fixed-price commitment.
Specifications
Structural parameters come from calculations and approved shop drawings
Steel structures are not a single standard product. Sections, plate thickness, connections, corrosion protection and fire requirements must follow the project design and responsible engineer's approval.
| Parameter | Project range / note |
|---|---|
| Thickness range | Plate and section thickness determined by structural calculation, connections and available material |
| Member width | Detailed as H-sections, box sections, trusses or built-up members |
| Custom length | Segmented for lifting capacity, containers and road-transport restrictions |
| Base material | Carbon or low-alloy structural steel; grade confirmed by design and material certificate |
| Surface treatment | Blast cleaning, primer and topcoat; hot-dip galvanizing or fire coating available where specified |
| Color range | Topcoat color confirmed with the project palette, coating system and maintenance plan |
| Design and execution references | SNI 1729:2020, SNI 1727:2020 and SNI 1726:2019 may apply; cold-formed members may use SNI 7971:2013. Approved design documents govern |
Applications
For industrial buildings and production-support structures
02
Warehouses and logistics
Regular grids and standardized members improve fabrication and erection efficiency.
03
Equipment platforms and mezzanines
Detailed around equipment loads, maintenance access and process clearances.
04
Canopies and links
Light steel solutions for loading zones, walkways and building connections.
Fabrication
Numbering, welding and dimensional control connect factory and site
Detailing, cutting, assembly, welding and coating are organized around the intended erection sequence to reduce site identification and rework.
Detailing and planning
Break down members, connections and bills of material around the erection sequence.
Cutting and assembly
Cut, drill and assemble components to the approved dimensions.
Welding and inspection
Complete qualified weld processes and specified visual or test checks.
Coating and marking
Apply surface preparation, coating and clear erection marks.
Packing and dispatch
Protect and load members in the planned site-lifting sequence.
Construction
Lifting stability, temporary bracing and final tightening are essential
Steel erection is specialist work. It must follow an approved lifting plan, connection procedure and safety plan; temporary support stays until the stable structural system is complete.
- 01
Verify foundation gridlines, levels, anchor bolts and component marks.
- 02
Use planned lifting points, temporary bracing and controlled work-exclusion zones.
- 03
Form a stable bay before final bolt tightening or site welding to the approved procedure.
- 04
Complete alignment, levels, connections, coating touch-up and handover inspection.
FAQ
What to prepare for a steel-structure enquiry
01Is pricing per kilogram or per square metre?+
Quotations may be compared by member weight, building area or package scope, but these bases are not directly interchangeable. Steel grade, span, connections, coating, transport and erection affect the total. Use an agreed material list and itemized quotation.
02Can I enquire without complete construction drawings?+
Yes. Start with the location, intended use, length, width, height, span and any sketch. KWD can help identify missing information. Structural parameters, calculations and construction documents still require the responsible engineer's approval; an initial discussion does not replace approved design.
03Are foundations, roofing and erection automatically included?+
No scope should be assumed. Confirm foundations and civil works, roof and wall cladding, steel members, coating, transport, lifting equipment and site erection separately, with responsibilities and costs recorded in the quotation.
04How long does project delivery take?+
Timing depends on drawing approval, procurement, member quantities, coating requirements, location and site readiness. A fixed delivery time cannot be promised before those details are checked.
05Can the structure be customized?+
Yes. Sections, connections, coatings, shipping splits and packing can follow approved drawings, with installation briefings where included.
06What is the warranty period?+
Coverage is defined separately for supply, coating and erection scope in the contract. Maintenance, corrosive exposure and third-party work affect applicability.
