Our product range includes aluminum, carbon steel, galvanized steel, stainless steel, copper, and titanium-magnesium alloy windows, with options for casement, sliding, fixed, awning, hopper, louver, ventilation, thermal insulation, sound insulation, fire-resistant, blast-resistant, and other application-specific designs. The following ordering process is intended to help international buyers communicate requirements clearly and complete each order efficiently.
Please send your inquiry with as much project information as possible. Clear specifications allow us to evaluate the application, recommend a suitable configuration, and prepare an accurate quotation.
Special-purpose windows require complete technical information. Performance-related requirements must be reviewed according to the product design, glass configuration, frame structure, hardware, installation conditions, and applicable project standards.
Most orders are quoted according to the confirmed dimensions, materials, glass configuration, hardware, finish, quantity, packaging, performance requirements, and delivery terms. If some details are not yet available, our team may request additional information or suggest practical options for comparison.
The quotation may include product descriptions, unit prices, quantities, packing information, estimated production arrangements, and applicable trade or delivery terms. Tooling, samples, testing, special documentation, or customized packaging will be stated separately when relevant. Prices remain subject to final technical confirmation and the validity period shown in the quotation.
Samples, finish swatches, hardware samples, drawings, or product mock-ups may be arranged when needed. Availability, cost, preparation time, and delivery charges depend on the requested item and level of customization.
Before ordering customized products, the buyer should review all relevant details, including dimensions, profiles, opening direction, glass, hardware, drainage, finish, accessories, installation interfaces, and packaging. A sample or drawing approval confirms the specified configuration but does not replace verification of site measurements or local project requirements.
An order proceeds after both parties have confirmed the commercial and technical details. Depending on the project, the confirmation documents may include a quotation, proforma invoice, purchase order, contract, product schedule, drawings, specifications, color references, and packing requirements.
Before approval, please carefully verify:
Production is based on the approved order information. Any requested change after confirmation will be reviewed for feasibility and may affect the price, production schedule, materials, or shipping arrangement. Changes should not be considered accepted until confirmed in writing by China Loong Metal Window Co., Ltd.
Payment terms are agreed according to the order value, customization level, production requirements, and commercial arrangement. The payment method, currency, payment stages, banking information, and any related conditions will be stated in the confirmed quotation, proforma invoice, or contract.
Buyers should use only the bank account information shown on an authorized commercial document and should verify any requested change to payment instructions through an established communication channel. Bank charges and transaction costs are handled according to the agreed terms. Production and shipment arrangements are subject to receipt and confirmation of the applicable payment.
Production is arranged according to the approved specifications and payment status. The schedule depends on product type, order quantity, material availability, technical complexity, required approvals, and current production planning. Any estimated completion or shipping date is subject to confirmation for the specific order.
During production, relevant updates, drawings, photographs, or approval requests may be provided when agreed or required. Products are checked against the confirmed order information before packing. The scope of inspection may include dimensions, appearance, opening operation, frame assembly, glass configuration, hardware, accessories, finish, quantity, and packaging.
If third-party inspection or project-specific testing is required, it must be communicated before order confirmation. The scope, standard, schedule, responsible party, and related cost must be agreed separately. Performance claims for fire-resistant, blast-resistant, acoustic, thermal, airtight, or other specialized windows must be based on the exact configuration and agreed technical documentation.
Packing is selected according to the window material, glass configuration, product size, transportation method, destination, and handling requirements. Protective film, corner protection, internal cushioning, cartons, wooden packing, pallets, or other suitable methods may be used as agreed. Buyers should advise us in advance of any destination-specific packaging, fumigation, labeling, or import requirements.
Shipment can be arranged by sea, air, courier, rail, road, or another agreed method, depending on the order and destination. Freight, insurance, customs clearance, import duties, taxes, port charges, and local delivery responsibilities are determined by the confirmed trade terms. Shipping dates may be influenced by carrier schedules, space availability, customs procedures, weather, and other factors outside the manufacturer’s direct control.
When China Loong Metal Window Co., Ltd. arranges transportation, the shipping documents will be prepared according to the agreed order details and information supplied by the buyer. The buyer is responsible for providing accurate consignee, contact, tax, and import information in time to avoid unnecessary delays or additional costs.
Upon delivery, the buyer should inspect the packaging, quantities, labels, glass, frames, hardware, and accessories promptly. Any visible damage or shortage should be recorded on the carrier’s delivery document when possible, and supporting photographs or videos should be taken before unpacking or installation.
If an issue is found, please contact us promptly and provide the order number, item reference, quantity affected, a clear description, photographs, videos, packaging condition, and relevant shipping documents. Products should be stored in a dry, secure location and handled in accordance with appropriate procedures for glass and fabricated metal products.
Correct installation is important to window operation, weather resistance, safety, and service life. Site openings, supporting structures, anchoring methods, sealants, flashing, drainage, tolerances, and local installation practices should be reviewed by qualified project personnel.
Unless installation services are expressly included in the confirmed order, the buyer is responsible for site measurement, unloading, storage, installation, adjustment, sealing, protection, and compliance with local building requirements. Installation guidance or product drawings may be provided where applicable, but site-specific engineering and regulatory approval remain subject to the project parties and local authorities.
China Loong Metal Window Co., Ltd. provides order-related support for product identification, installation questions, operation, maintenance, replacement parts, and reported quality concerns. Each matter is reviewed according to the confirmed specifications, supplied evidence, product condition, installation details, use environment, and agreed order terms.
For efficient handling, please do not dispose of damaged parts, packaging, labels, or shipping records before the issue has been reviewed. Where a replacement, repair, technical adjustment, or other resolution is appropriate, the arrangement will be confirmed based on the circumstances of the individual case.
Every project may involve different technical, commercial, and logistical requirements. The final quotation, proforma invoice, sales contract, approved drawings, and written correspondence for a specific order take precedence over general information on this page. No verbal change is binding unless it is confirmed in writing by authorized representatives of both parties.
To begin an order, please send your product list, window schedule, drawings, dimensions, material preferences, performance requirements, quantity, and destination. Our team will review the information and respond with the next steps for technical confirmation and quotation.
