How Mettle Works
Three steps from spec to site.
01
Tell Us Your Spec
Share your material type, quantity, delivery location, and any required certifications or DOT designations. No spec sheet required to start.
02
We Match & Document
We identify qualified aggregate sources, confirm availability, pull the right DOT and ASTM documentation, and assign a named sales representative to your opportunity.
03
Delivered to Your Site
Coordinated truck, rail, barge, or vessel delivery across the Eastern corridor to the Gulf — on your project timeline, at a competitive delivered price.
Why Mettle Materials
Built for buyers who need it right the first time.
DOT & ASTM Documentation
Gradation, LA abrasion, absorption, resistivity, and reactivity records available on qualification. Controlled copies standard. Source docs released for qualified project review.
Bulk & Project Volume
Scalable supply from single loads through recurring project tonnages. No artificial volume cap. We work with your schedule, not against it.
Multimodal Logistics
Coordinated truck, rail, barge, and vessel delivery across the Eastern corridor to the Gulf. We match the delivery mode to your site access and budget.
Controlled Compliance Documents
