--- title: "Custom Aluminum Windows & Doors for US Projects" description: "Plan a factory-direct window and door inquiry for your US project. Share the opening schedule, project requirements and delivery destination." slug: "markets/united-states" noindex: false --- Custom Aluminum Windows & Doors for US Project Buyers Source project-configured windows and doors directly from ENGGIA’s own factory. Explore the product ranges and send your opening schedule to discuss the requirements for your destination. Custom aluminum windows and doors for trade and project procurement. We also accept personal custom aluminum window orders. For importers, distributors, contractors, project buyers and homeowners planning custom aluminum windows. [Discuss a US Project](/request-a-quote/#quote-form) ## From Your First Idea to Delivery A photo, a rough sketch or approximate dimensions are enough to start a conversation. Tell us what you want to achieve and which details are still undecided. Final sizes and configuration will be confirmed before production. ### 1. Share your opening requirements Choose an [opening type](/products/), or send a reference photo. Include quantities, dimensions with units and your US state and delivery location when known. Use the [RFQ checklist](/resources/window-door-rfq-checklist/) if you already have a detailed schedule. ### 2. Confirm drawings, configuration and scope Review the proposed frame, glazing, finish, hardware, dimensions and opening direction with your builder or installer. Match required documents to the selected configuration, then agree the quotation, payment terms and production schedule. Ask about a sample if you need to evaluate a configuration first. ### 3. Plan production and quality checks We implement strict quality control throughout the entire production process, including raw material inspection, profile machining, assembly, glazing, hardware installation, performance checking, and final inspection before packing. Key items such as dimensions, surface finish, glass quality, hardware operation, sealing performance, and overall workmanship are carefully checked to ensure each product meets the approved drawings and order requirements. Sample production: 10–35 calendar days. Bulk production: 25–45 calendar days. Production lead times do not include transport or import clearance. Confirm the production start, final schedule and delivery scope with your quotation. ### 4. Agree packing, transport and handover We provide professional export packing and worldwide shipping support. Products are securely packed with protective film, foam, cartons, plywood cases, or timber frames according to product size and transportation requirements. We can assist with container loading, export documentation, and international shipping arrangements under commonly used trade terms such as FOB, CFR, and CIF. Record the named handover point and who arranges freight, import clearance, taxes, onward delivery and unloading. Review these inclusions in the quotation before comparing delivered costs. ### 5. Prepare for receipt and local installation Coordinate access, unloading, storage and installation with your local team. Check package labels and quantities on arrival, and photograph their condition. Confirm installation responsibilities in the order scope. Use the [packing and receiving checklist](/resources/window-door-export-packing-delivery-checklist/) to prepare. ### 6. Keep an order reference for follow-up Keep the agreed drawings, opening IDs and order reference. If a question arises after delivery, [contact our team](/request-a-quote/) with the affected opening or component and photos. Confirm warranty terms, replacement freight and any site work responsibilities in writing with the order. ## Organize Your US Project Inquiry | Include | Why it matters to the proposal | | --- | --- | | State and delivery location | Identifies the destination and requested delivery scope | | Inches or millimeters | Makes the dimension basis clear throughout the schedule | | Frame or structural-opening sizes | Separates the product dimensions from the installation opening | | Project performance values with units | Keeps the required values distinct from catalogue descriptions | | Requested document references or specifications | Identifies the evidence the project team wants to review | | Local installation interfaces | Clarifies which details need coordination with the installer | ## Choose the Opening Types Explore [Sliding Doors](/doors/sliding-doors/), [Bifold Doors](/doors/bifold-doors/), [Awning Windows](/windows/awning-windows/), [Sliding Windows](/windows/sliding-windows/) and [Casement Windows](/windows/casement-windows/). List different types separately in a mixed project schedule. ## Share the Project Requirements Include the project’s requested performance values and units, any required product documentation, and the installation scope handled by your local team. If dimensions are in inches, identify them clearly on the schedule. ## Review Documents Against the Configuration Ask for the documents relevant to the proposed series, dimensions and glazing. A document for one product should not be assumed to cover every item in a mixed order. ## Define the Delivery Scope Provide the state and delivery location. Clarify packing, freight arrangements, import responsibilities and any excluded items when reviewing the quotation. ## Keep Units and Documents Consistent If the project uses both imperial and metric values, identify the controlling units. A thermal-performance figure should state whether it describes the glass or the complete product, and the proposed configuration should be read with the relevant document. [Product Certificates & Test Reports](/technical-documents/) [Prepare Your RFQ](/resources/window-door-rfq-checklist/) ## Send Your Project Schedule Include the product types, quantities, dimensions and any requirements that are already fixed. [Request a Project Quote](/request-a-quote/#quote-form) ## Prepare a configuration-specific document request Our public collection includes a CSA certificate preview and an AAMA bifold-door test preview. Send the project requirements, selected catalogue ID and configuration so the complete records can be reviewed. Neither preview establishes blanket approval for a US project. [Match the document to the order](/resources/how-to-read-window-door-test-reports/) [Agree delivery and receiving responsibilities](/resources/window-door-export-packing-delivery-checklist/) ## How do I start a factory-direct inquiry for a US project? Send the product types, quantities, sizes and destination state. Include the project specifications and local installation requirements you already have. We will discuss the proposed configuration and supply scope from our own factory. ## Can I submit US project dimensions in inches? Yes. Clearly label the units and specify whether they describe the frame or the structural opening. If the schedule also contains metric dimensions, identify the controlling values so conversions do not introduce ambiguity. ## Do all the catalogue products have the same US certification? Documents cover named products and configurations. Identify the documentation your project requires and review the relevant record. A label or report for one series should not be applied to another by assumption. ## Are impact-resistant or hurricane-related requirements automatically included? No. If the project specifies impact or other exposure-related requirements, include the exact specification and required evidence in the inquiry. A general wind-performance or thermal document should not be treated as proof of a different performance claim. ## Does the inquiry include local installation? Include your local installation arrangements and required interfaces in the inquiry. Installation is not automatically included in a product quotation; responsibilities should be stated in the proposed scope. ## What is needed to discuss delivery costs? Provide the destination state and delivery location or port when known, plus the product schedule and requested delivery scope. Freight and import-related items must be identified in the quotation rather than assumed to be included in the product price.
