FAQ
What are your typical lead times?
Lead times are typically 2-4 weeks for mill production. We can often ship standard stock items within a few days.
What is your Minimum Order Quantity (MOQ)?
Our MOQ is generally 500kg per specification, but it can be flexible for standard stock items. Please contact us with your requirements for a specific confirmation.
Do you provide a Material Test Certificate (MTC)?
Yes, every shipment is accompanied by our MTC, detailing the chemical composition, mechanical properties, and compliance with the ordered standard.
How do you package the aluminum bars to prevent damage during shipping?
Our bars are carefully bundled, wrapped in protective film, and packed in sturdy wooden cases or on pallets to ensure they arrive in perfect condition.
What dimensional tolerances and machining services does HXM Aluminum support for custom square bars?
As an ISO 9001:2015 certified manufacturer, HXM Aluminium offers advanced factory-direct processing to provide components ready for immediate use on assembly lines. Our capabilities include:
Precision length cutting: Custom lengths from 1000 mm to 6000 mm, with tight linear tolerances down to ±0.5 mm.
Secondary tooling services: Multi-axis CNC machining, high-speed drilling, tapping, chamfering, precision laser cutting, and deburring.

Which industries are the largest consumers of aluminum square bars?
Marine, transportation, construction, manufacturing equipment, and architectural projects.
Which aluminum alloy and annealing condition should I choose for my square bar project?
The best alloy choice depends entirely on your mechanical and environmental specifications:
Choose 6061-T6 if your project requires a versatile material that provides high strength, reliable structural weldability, and excellent CNC machining characteristics.
Choose 7075-T6 when your application operates under extreme mechanical stress or requires maximum yield strength and superior resistance to fatigue cracking, such as aerospace hardware or high-precision die-cutting tools.
Choose 6063-T5/T6 for building or decorative projects where mechanical stress is secondary, second only to excellent, flawless native or anodized finishes. For marine applications, choose 5052 or 5083, which require long-term structural integrity and excellent resistance to localized saltwater corrosion.
Do you provide surface finishes suitable for outdoor installations?
We offer anodizing, powder coating, and other protective finishes for extended outdoor performance.
Is CNC machining available for large-volume orders?
Yes, we can process bars into ready-to-use components at our machining facility.
Can aluminum square bars be anodized?
Yes. Most aluminum square bars can be anodized to improve corrosion resistance and appearance.
What standards do your aluminum square bars comply with?
Our products can comply with ASTM B221, EN 755, AMS, and other international standards.
