Common buyer questions
01What information is needed for a steel structure building quotation?
Please provide the building use, length, width, height, delivery country, wind and snow load if known, roof and wall material, door and window positions, crane requirement and any available drawings. A complete brief makes the steel quantity, enclosure materials and freight plan more reliable.
02What is the difference between portal frame and multi-storey steel buildings?
Portal frame buildings are common for single-storey workshops, warehouses and agricultural buildings. Multi-storey steel buildings need more attention to floors, columns, beams, fire requirements and local engineering approval.
03Do steel structure projects need local engineer review?
Usually yes. Wind load, snow load, seismic rules, fire approval and permit requirements differ by country and region. HIH Steel can support material and product scope, while local compliance should be confirmed by qualified professionals.
01What is the difference between EPS, rock wool, PU and PIR sandwich panels?
EPS is often used for economical enclosure. Rock wool is preferred where fire performance is important. PU and PIR provide stronger thermal insulation and are often used for cold rooms, cold chain buildings and energy-saving envelopes.
02Can wall sandwich panels and roof sandwich panels be used interchangeably?
Not usually. Roof panels must consider slope, overlap, water drainage, wind uplift and roof load. Wall panels focus more on facade finish, insulation, fire performance, openings and trim details.
03How should I choose cold room panel thickness?
Panel thickness depends on target temperature, outside climate, room size, door opening frequency and energy requirements. Provide these details so HIH Steel can recommend PU, PIR or another suitable cold room enclosure option.
04What is different about clean room sandwich panels?
Clean room panels focus on flat surface, clean joints, sealing, easy cleaning and matching with clean room doors, windows, aluminum profiles and corner accessories. The choice should follow the room function and cleanliness requirements.
05How do I choose roof and wall materials for a steel building?
Consider climate, insulation requirement, fire performance, building use, budget, appearance and maintenance. Warehouses may use corrugated sheets or sandwich panels, while cold rooms and clean rooms need more specialized enclosure systems.
06Are modular houses different from ordinary steel structure buildings?
Modular houses focus on fast installation, repeatable units and transport efficiency. Ordinary steel buildings are usually designed for long-term workshops, warehouses, commercial or public buildings.
01Can HIH Steel quote before complete drawings are ready?
Yes, a preliminary budget can be prepared from basic dimensions, use, destination and material preference. Before production, final drawings, specifications, quantities and packing details still need confirmation.
02Can products be customized by drawings?
Yes. Steel components, panel lengths, panel profiles, colors, cold room panels, clean room enclosure systems and accessories can be customized after drawings and specifications are confirmed.
03What documents help prepare an accurate quotation?
Useful documents include drawings, quantity lists, target temperature, panel core preference, color, coating, destination port, packing requirement and any certificate or local code requirement.
04Does HIH Steel provide installation guidance?
HIH Steel can provide product installation notes, project communication and detail suggestions for confirmed materials. Site installation should still be organized by qualified local teams according to local rules.
05Can certificates and test reports be provided?
Available certificates, test reports or company documents can be provided according to the confirmed product and project requirement. Please confirm the exact standard and destination requirement before ordering.
06How long is delivery time?
Delivery time depends on product type, quantity, customization, factory schedule, packing method and shipping route. The schedule should be confirmed after drawings, material list and payment terms are settled.
07How are export products packed?
Steel components are bundled and marked; sandwich panels are stacked and protected; modular buildings are packed according to folded, containerized or assembled delivery mode. Loading photos and packing records can be provided.
08Can doors, windows, trims, purlins and accessories be supplied together?
Yes. HIH Steel can coordinate related materials such as purlins, floor decks, trims, fasteners, doors, windows and sealing accessories according to the project scope.
09Can HIH Steel provide loading photos?
Yes, loading photos and packing records can usually be provided for confirmed export orders. They help buyers check package count, marks and cargo condition before arrival.
10What is covered by warranty?
Warranty scope depends on the product, contract, installation method, storage condition and use environment. Keep order documents, photos and installation records so any issue can be reviewed clearly.
11What is the best way to get an accurate quote quickly?
Send dimensions, use, drawings, delivery country, preferred materials, quantity, target schedule and special requirements in one message. The clearer the first inquiry, the faster the technical and commercial reply.
