High-quality products tailored for wholesalers and distributors worldwide.
China Loong Steel Structure Co., Ltd. supplies fabricated steel structure components, connection hardware, roofing and wall systems, sandwich panels, and finished steel products for international B2B projects. The following ordering process helps buyers communicate technical requirements, confirm commercial terms, and coordinate production and delivery efficiently. Product specifications, prices, payment arrangements, production schedules, and shipping terms are confirmed separately for each order.
Please send an inquiry with sufficient information for us to identify the required product and prepare an accurate response. We can discuss standard or customized requirements for products such as steel beams, columns, trusses, purlins, bracing, mezzanine components, crane beams, floor decks, structural bolts, anchor bolts, embedded parts, roof and wall panels, sandwich panels, canopies, carports, and related steel building components.
Where applicable, please provide the following details:
If complete drawings are not available, buyers may submit sketches, dimensions, photographs, or a general project description. Additional technical information may be requested before quotation or production.
After receiving the inquiry, we review the specifications, fabrication requirements, quantities, and intended application. Customized products may require clarification of material grades, welding details, bolt grades, hole patterns, panel profiles, insulation materials, surface treatment, dimensional tolerances, and assembly interfaces.
Any technical review, drawing discussion, or manufacturability feedback is intended to support order preparation. Unless specifically agreed in writing, the buyer remains responsible for confirming that the selected products, dimensions, structural design, and applicable standards are suitable for the project and comply with local regulations.
Our quotation is prepared according to the confirmed product requirements and available technical information. Pricing may depend on material specifications, dimensions, fabrication complexity, surface treatment, quantity, packaging, destination, freight conditions, and other order-specific factors.
A quotation may include:
Freight rates, raw material prices, exchange rates, and other variable costs may change. If an order is not confirmed within the quotation validity period, updated pricing may be required.
Samples, shop drawings, color references, or other approval materials may be arranged when required and feasible. Availability, cost, preparation time, and delivery arrangements are confirmed according to the product and project requirements.
For customized fabrication, production may be based on approved drawings, specifications, samples, or written technical confirmations. Buyers should carefully review dimensions, quantities, materials, hole positions, connection details, surface finishes, markings, and other critical information before approval. Requested changes after approval may affect price, material usage, production progress, and delivery timing.
An order is considered ready for processing after the technical and commercial details have been agreed in writing and the applicable payment or other agreed conditions have been completed. Confirmation documents may include a purchase order, proforma invoice, sales contract, approved drawing, bill of materials, product specification, or written email confirmation.
Before confirming the order, both parties should verify:
Changes requested after order confirmation are subject to review. China Loong Steel Structure Co., Ltd. will advise whether the change is feasible and whether it affects pricing, production arrangements, completed work, or delivery timing. Production changes should not be treated as accepted until confirmed in writing.
Payment currency, method, schedule, bank charges, and any staged payment arrangement are agreed according to the order value, product type, customization level, and commercial terms. The applicable requirements will be stated in the proforma invoice, sales contract, or other confirmed order document.
Payments should be made only to the bank account formally specified by China Loong Steel Structure Co., Ltd. If bank information appears to change, buyers should verify the change through an established communication channel before arranging payment. Production, document release, or shipment may be scheduled according to receipt of the agreed payment and completion of other order conditions.
Production is arranged according to the confirmed specifications, approved documents, material availability, and workshop schedule. Estimated lead times are provided for planning purposes and are subject to confirmation based on actual order details.
For project-based or customized orders, progress updates may be provided at agreed stages. Depending on the products and order requirements, communication may cover material preparation, cutting, drilling, welding, surface treatment, panel production, trial assembly, packing, or readiness for shipment. Photographs or videos may be provided when agreed, but they do not replace a specified inspection procedure.
Products are checked against the confirmed order documents and applicable inspection requirements. The scope of inspection may include dimensions, quantities, appearance, fabrication details, hole positions, surface treatment, packaging, and other specified items, depending on the product.
If the buyer requires third-party inspection, special testing, material documentation, inspection reports, or a pre-shipment review, these requirements should be stated before quotation and order confirmation. Related costs, scheduling, acceptance criteria, and document formats must be agreed in advance.
Reasonable manufacturing and measurement tolerances may apply according to the confirmed drawings, product specifications, agreed standards, and manufacturing process. Any project-specific acceptance criteria should be provided before production begins.
Packing is selected according to product size, weight, surface protection needs, handling method, transport route, and buyer requirements. Steel components may be bundled or otherwise secured for shipment, while panels, fasteners, and smaller parts may require separate protective packing. Special pallets, crates, moisture protection, edge protection, export markings, or package numbering can be discussed before order confirmation.
Buyers should advise us of any limitations related to container loading, forklift access, crane unloading, maximum package dimensions, maximum package weight, warehouse handling, or local packaging rules. Special packing requirements may affect cost and preparation time.
Delivery may be arranged by sea, land, air, courier, or multimodal transport, depending on the product dimensions, shipment volume, destination, and commercial terms. The applicable Incoterm, loading point, destination, freight responsibility, insurance responsibility, and customs documentation will be stated in the confirmed order documents.
Shipping dates and transit times are estimates unless otherwise agreed in writing. Actual timing may be affected by production conditions, booking availability, carrier schedules, port operations, customs procedures, weather, and other circumstances outside the manufacturer’s direct control.
The buyer is responsible for providing accurate consignee details, contact information, import instructions, and destination requirements in time for shipment. Import licenses, duties, taxes, customs clearance, local inspection, unloading, and inland delivery are handled according to the agreed trade terms.
Upon delivery, the buyer should inspect the packages before signing the carrier’s receipt. Any visible package damage, shortage, deformation, or water exposure should be recorded with the carrier and supported by clear photographs or video.
After unloading, products should be checked against the packing list and confirmed specifications. Components should be stored using appropriate supports and protection from moisture, contamination, impact, and distortion. Roof panels, wall panels, sandwich panels, coated steel products, and fabricated components should be handled carefully to avoid scratches, bending, or damage to protective finishes.
If a product appears to differ from the confirmed order, please contact China Loong Steel Structure Co., Ltd. promptly after receipt and before installation, modification, or further processing. The notice should include the order number, item description, affected quantity, package marks, photographs or video, measurements, and a clear explanation of the issue.
We will review the information against the approved drawings, specifications, inspection records, packing documents, and shipping condition. The appropriate response will depend on the verified cause, the nature of the issue, the condition of the products, and the agreed order terms. Buyers should retain the products, packaging, labels, and relevant evidence while the review is in progress.
After-sales communication may also include clarification of component identification, packing lists, assembly references, replacement part requirements, or repeat-order specifications. Any installation or engineering support must be specifically discussed and confirmed according to the project scope.
Requests to change, suspend, or cancel an order must be submitted in writing. Approval depends on the production stage, purchased materials, completed fabrication, customized work, packaging, logistics bookings, and other costs already incurred.
Customized or fabricated products may not be suitable for resale or reuse. Therefore, any refund, credit, additional charge, or revised delivery arrangement related to a change or cancellation will be evaluated according to the specific order status and confirmed in writing.
Product specifications, approved drawings, purchase orders, proforma invoices, sales contracts, and written amendments should be reviewed together. If information is inconsistent, both parties should clarify the discrepancy in writing before production or shipment.
The final order terms are those stated in the mutually confirmed commercial and technical documents. These general guidelines support the ordering process but do not replace the specific terms agreed for an individual transaction.
