Structural Evaluation & Material Breakdown

Corrosion Resistance: Frame and corrugated panels utilize SPA-H weathering steel, eliminating the need for primary rust treatment during initial site deployment. Total dry film thickness (DFT) reaches 120 to 150 microns, verified via 1,000-hour salt spray testing (ASTM B117).

Frame & Corner Castings: ISO 1161 compliant forged steel corner castings support top-lift and bottom-lift handling when fully loaded up to 32.5 metric tons. Corner posts are cold-rolled from 4.5 mm thick structural steel sections.

Welding Standards: All structural seams undergo continuous CO2 gas-shielded arc welding performed by AWS D1.1 / ISO 9606 certified welders. Ultrasonic testing (UT) and dye penetrant inspection (PT) are applied to critical load-bearing joints.

Floor Reinforcement: Standard 28-mm Apitong or marine-grade hardwood plywood floor is screw-fastened to cross-members spaced at 300-mm intervals, supporting heavy point loads from pallet jacks and forklifts. Steel checker plate overlays are available for heavy machinery footprints.

Application Matching

BESS & Generator Enclosures:

Extra headroom allows routing of overhead cable trays, exhaust ducting, and fire suppression piping without obstructing internal walkways.

Tool & Spare Parts Depot:

High vertical volume accommodates multi-tier cantilever racking for long pipes, valves, and heavy replacement assemblies.

Mobile Workshop Integration:

Compatible with custom interior fit-outs, including electrical distribution boards, HVAC cutouts, workbench anchoring channels, and personnel access doors.

Supplier Evaluation & Manufacturing Capabilities

Production Facility:

45,000 square meters automated manufacturing plant equipped with CNC plasma cutting lines, hydraulic press brakes (up to 500 tons), and automated shot-blasting booths.

Quality Control Protocol:
Dimensional tolerance check on frame squareness (+/- 2 mm).

Water tightness testing via high-pressure water jet test (BS EN ISO 1496-1 standard, 100 kPa pressure nozzle testing).

Paint adhesion cross-cut test (ISO 2409 Class 0-1).

Traceability:

Raw material mill test certificates (MTC) and third-party inspection reports (ABS/BV witness records) provided upon shipment.

Procurement Decision Guide

Determine Dimensional Requirements: Verify whether internal height clearance (2,690 mm) accommodates your tallest equipment skid plus overhead rigging clearance.

Define Customization Scope: Specify required modifications upfront (e.g., personnel doors, ventilation louvers, insulation, partition walls, electrical packages) to avoid post-delivery structural cutting.

Confirm Regulatory Compliance: Check if site destination requires specific classification society certification (e.g., ABS, BV, DNV) or CSC safety plating for intermodal transport.

Inquire Lead Time & Logistics: Standard production lead time is 25 to 35 days for container units. Shipping can be arranged as empty intermodal cargo or packed with customer-supplied machinery (factory-loaded OEM service).

FAQ

Q: What is the exact internal height difference between a Standard and High Cube equipment container?

A: A standard container provides an internal height of approximately 2,390 mm (7'10"), whereas a High Cube container provides 2,690 mm (8'10"), giving you an additional 300 mm (12 inches) of vertical clearance for taller machinery, vertical pumps, or overhead cable trays.

Q: Can the container floor support heavy tracked or wheeled machinery?

A: Yes. The standard floor cross-members are spaced at 300-mm intervals, rated for a forklift axle load of 4,500 kg. For heavy tracked equipment or concentrated point loads exceeding standard limits, we weld an additional 4-mm steel checker plate over the marine plywood substrate.

Q: How do you prevent condensation inside equipment storage containers in humid climates?

A: We offer optional thermal insulation packages comprising 50 mm rockwool or polyurethane foam panels enclosed by pre-painted galvanized steel interior sheets, combined with gravity or mechanical louvered ventilation to maintain airflow and prevent moisture accumulation.

Q: Are these containers certified for international ocean freight transport?

A: Yes. All units are built in accordance with ISO 668 and ISO 1496-1 standards and are issued a valid CSC (Convention for Safe Containers) safety approval plate upon completion of structural load testing.

Q: What is the standard corrosion protection system used on exposed exterior surfaces?

A: The bare steel is first abrasive blast-cleaned to Sa 2.5. It is then coated with an inorganic zinc-rich epoxy primer (>= 70 microns), followed by an intermediate epoxy build coat and a final polyurethane (PU) topcoat, achieving a total dry film thickness of 120 to 150 microns designed for aggressive industrial and marine environments.
