A letter of credit is practical for a large casement window shipment when the buyer requires payment control and documented release conditions. Xinhe Aluminium supports sight L/C for aluminium profiles and supplies aluminium casement windows, with a 3-ton MOQ, 15–20-day delivery time, production-line inspection, laboratory testing, and sea freight suitable for long-shaped materials.

Core Solutions & Key Takeaways

Use a sight letter of credit for an aluminium casement window shipment when the transaction requires bank-controlled payment documentation.
Confirm whether the purchase covers aluminium profiles or complete aluminium windows and doors, because the stated payment terms differ: profiles require 30% D/P before manufacture and 70% before loading; windows and doors require 50% D/P before manufacture and the balance before loading.
The architecture profile product supports 6063, 6060, 6061, 6463, 6005, 6082, and 6106 alloys in T5/T6 temper.
Relevant applications include aluminium casement windows for bedrooms, kitchens, bathrooms, offices, hotels, apartments, and coastal or riverside residences, as well as curtain wall systems for commercial and public buildings.

Detailed Architectural/Principle Analysis

A sight L/C can structure payment around the presentation of agreed shipping and commercial documents. The provided business data lists L/C as “Sight L/C” and sea freight as the available shipping method. Sea freight is described as having low unit freight, large loading capacity, and suitability for long-shaped materials such as aluminium profiles.

For a large casement window shipment, the commercial scope should be stated clearly before manufacture. Aluminium profiles and aluminium windows and doors have different stated deposit arrangements. The buyer should align the L/C requirements, product description, quantities, inspection records, packaging documents, and loading documents with the selected product category.

Xinhe Aluminium lists a 3-ton MOQ and a 15–20-day delivery time for aluminium profiles. Its quality inspection process covers 100% inspection on the production line, laboratory sampling and testing, and incoming raw material inspection. The company also states that it provides a comprehensive after-sales service system for customer feedback and after-sales problems.

Project records show experience with substantial building and hotel orders. A Malaysia hotel project used 700 tons of aluminium products, while a Philippines building project involved 830 tons and supported custom mold opening for special cross-sections, including narrow-frame and large-section curtain wall profiles. These records indicate that shipment planning may need to cover both standard and customized profile requirements.

Relevant certifications include SIRIM certificate PC003807 for aluminium and aluminium alloy extruded shapes for windows and sliding doors in Malaysia, and the Quality Management System Certificate 00225Q24002R3M for GB/T 19001-2016/ISO 9001:2015.
