Find the closest aluminum project reference for your drawing
Use Conglin project experience to move from an idea, drawing or sample photo to a clearer quotation route. You can compare railway, bridge, forging and marine references, then send your alloy, size, quantity, approval document and delivery requirements.
Project experience across rail, power, vehicle and industrial applications
Use these reference logos as a quick trust signal before customers choose the matching project route and send drawings for review.

Each project route leads to a detailed Conglin reference page with photos, application notes and production details. If your requirement covers more than one route, use the RFQ form and Conglin will help you classify it.
Railway aluminum profiles and train carbody parts
Plan profile supply, machining, surface treatment and packing around your railway drawings, spare parts list or replacement schedule.
Aluminum pedestrian bridge structures
Share your span, load, railing, deck and installation plan so Conglin can review a practical fabrication and supply route.
Aluminum forging for high-load parts
Use Conglin when your part needs forged strength, machining allowance, heat treatment, inspection proof and controlled production.
Aluminum shipbuilding and marine workboats
Send your vessel drawings, alloy requirements, welding needs and certification expectations for marine fabrication support.
Use one collection to prepare a faster aluminum RFQ
Keep the discussion practical: application, alloy, dimensions, processing, tolerance, quantity, destination and approval documents. When you already know the matching project route, click the project details. When you are not sure, send your drawing directly.
Confirm how Conglin can support your project from material preparation to finished delivery
Reference the production technology route when your quotation needs casting, mold making, extrusion, CNC machining, forming, welding, inspection or export packing.
Casting and billet preparation
Start your custom aluminum project from controlled casting and billet planning.
In-house mold making
Use mold design, CNC machining and die preparation to reduce communication gaps before extrusion.
Extrusion and CNC capacity
Match large extrusion, CNC machining and forming capacity with your project specification.
Review real application photos before you send your drawing
Use image-and-text project cases to explain your application faster. Conglin can then align the quotation around material strength, profile size, machining depth, welding, surface protection and export packing.
Rail transit bus bar installation
Review aluminum conductor, profile and spare-part supply for rail transit maintenance or new-build programs.
Urban pedestrian bridge system
Check deck, railing, crossbeam and underdeck details when your project needs a lighter construction structure.
Marine workboat production
Use vessel references to discuss hull structure, welding sequence, alloy choice and proof documents.
Prepare the details that help your quotation move faster
Send your drawing or sample photo with the application background. Include alloy or standard, dimensions, tolerance, surface finish, machining or welding needs, quantity, destination and required proof documents.
Check the details Conglin needs for a practical quotation
The table is horizontally scrollable on mobile so your team can continue reviewing every requirement.
| RFQ area | What you can send | Why it matters | Quote action |
|---|---|---|---|
| Drawing | CAD, PDF, STEP, sketch, sample photo | Confirms shape, tolerance, machining and tooling risk | Upload in the form |
| Application | Railway, bridge, forging, marine or other use | Helps Conglin choose the correct production and inspection route | Add project notes |
| Material | Alloy, temper, standard, surface finish | Supports accurate cost, feasibility and approval documents | List available requirements |
| Logistics | Quantity, destination port, packing, deadline | Improves delivery planning and export packing choices | Send target schedule |
Quality proof before your order
Conglin supports international procurement teams with quality-system certificates, welding qualifications, inspection records and export-ready documents. The goal is simple: help your engineering, purchasing and compliance teams reduce supplier risk before production starts.
Recognized systems for supplier approval
When you compare suppliers, certificates help confirm whether a factory can support controlled production, documented welding, inspection and shipment paperwork. Conglin prepares these documents so your RFQ review is faster and more transparent.
