Our products

Mortar Packaging

Our spiral-wound, waterproof fibre tubes are the trusted industry standard for mortar packaging. Designed to ensure safe handling, transport and storage, they provide excellent protection against impact, moisture and environmental stress. Available in standard formats for 60mm, 81mm and 120mm mortars, each tube is engineered for precision, durability and full compliance with defence specifications.

Tank & Artillery Packaging

Developed for the secure packaging of 105mm ammunition used in tanks and artillery systems, our heavy-duty cardboard tubes ensure optimal protection during handling, storage and transport. Engineered with reinforced spiral-wound construction and moisture-resistant coatings, they maintain structural integrity under mechanical stress and varying environmental conditions. Our 105mm ammunition family includes a wide range of models, also made to your requirements.

Calibre ammunition packaging 76/62mm

Our custom-engineered fibre tubes for 76/62mm calibre ammunition offer robust, reliable protection for naval and ground-based defence systems. Built with high-strength spiral-wound construction and water-resistant barriers, they are designed to safeguard rounds from impact, humidity and environmental exposure. Precision-crafted to meet strict military requirements, these tubes ensure secure storage and transport in even the most challenging operational contexts.

MIL-C-2439 standard – Fiber Containers

Our fiber containers manufactured to MIL-C-2439 specifications are designed to meet the rigorous requirements standards. Constructed from high-strength spiral-wound fibreboard, these containers provide robust protection against impact, moisture, and environmental stress.

They are ideal for the packaging of explosive materials, ammunition, and other mission-critical components.

Accessories

To ensure maximum safety and stability during handling, transport and storage, CSM Defence offers a range of accessories that complement our fibre tubes and containers.

Wooden or plywood crates

Available in solid wood or durable plywood, our custom crates are designed to house fibre tubes securely, providing an extra layer of protection during long-distance shipping or extended storage.

Plastic support for 76-62

Specifically designed for 76/62mm calibre rounds, this rugged plastic support stabilizes the ammunition inside the tube, preventing movement, impact and abrasion during handling and transport.

Tailor-made plastic support

We suppply custom plastic supports to meet the exact geometry and protection requirements of various calibres and components. These elements ensure a precise fit, secure positioning and optimal protection, even in high-vibration or long-range logistics scenarios.

Accessories fiber container components

Custom-shaped inserts that stabilize and isolate the payload within the container, reducing movement and vibration during transport or handling.

Customization

Tailored to your mission

We work alongside procurement teams, system integrators and manufacturers to develop tubes that meet strict defence standards and environmental constraints. Customization options include:

Internal and external diameter
Wall thickness
Length and cutting precision
Paper types and adhesives
Coatings, linings and closures

All solutions are tested and validated to ensure performance under pressure, vibration and variable climate conditions.
