Not All Tool Boxes Survive Real Work

Generic retail boxes fail under commercial pressure. Our fleet-grade construction delivers the durability and weather protection your operations demand—year after year.

Standard Retail Boxes

Why Cheap Boxes Fail Your Fleet

  • Thin-gauge sheet metal — Dents easily, corners crack under load
  • Basic snap latches — Break within months of daily use
  • No weather sealing — Water damage ruins tools and equipment
  • Prone to corrosion — Rust compromises structural integrity
  • Generic fitment — Requires modifications for installation
Brontec Fleet-Grade

Built for Multi-Year Daily Abuse

  • Reinforced aluminum structure — 6061-T6 alloy resists impacts and heavy loads
  • Heavy-duty latch system — Industrial-grade hardware survives constant use
  • Weather-sealed gaskets — Complete protection from rain, dust, and debris
  • Corrosion-resistant aluminum — Maintains integrity in harsh conditions

Common Questions

Frequently Asked Questions

Get answers to the most common questions from fleet managers and OEM buyers about our tool box manufacturing capabilities.

Do you design or manufacture based on drawings?

We specialize in build-to-print manufacturing. You provide the drawings and specifications, and we manufacture to your exact requirements. Our engineering team can also assist with design optimization for manufacturability while maintaining your specifications.

Can you customize dimensions and mounting holes?

Absolutely. Every tool box is manufactured to your specific dimensions, mounting hole patterns, and vehicle fitment requirements. We use CNC precision machining to ensure exact hole placement for bolt-on installation.

What aluminum grades do you use?

Our standard production uses 6061-T6 aluminum alloy, which offers excellent strength-to-weight ratio and natural corrosion resistance. We can also work with other aluminum grades based on your specific requirements and specifications.

Are boxes waterproof?

Yes. Our tool boxes feature continuous weld seams and EPDM rubber gaskets that provide complete weather sealing. Every unit is pressure-tested before shipping to verify water-tight integrity for protection against rain, snow, and road spray.

What is MOQ for OEM orders?

MOQ varies based on product complexity and customization level. For standard OEM orders, we typically require a minimum of 50 units. For highly customized specifications, we can discuss flexible arrangements. Contact us with your requirements for specific pricing.

How are boxes packed for shipment?

Tool boxes are individually wrapped in protective film, then secured on wooden pallets with corner protection. Packaging is engineered to withstand ocean freight handling. We can also provide custom packaging with your branding for retail-ready shipments.

Can you support long-term fleet supply?

Yes. We specialize in long-term OEM partnerships with consistent, repeatable production. Once your specifications are locked, we maintain tooling and production documentation to ensure every batch matches approved samples—year after year.
