As global supply chains demand higher structural accountability, Jagruthi Prefab Solutions Private Limited (operating under the global brand JPS Box Homes, CIN: U16222AP2025PTC121560) stands out as an established industrial manufacturer of prefabricated modular structures. We specialize in producing CE-certified container cabins, demountable site offices, flat-pack units, folding modules, glass curtain-wall pavilions, and heavy steel structure buildings for global contractors, project developers, and institutional buyers.
Operating manufacturing facilities located across Andhra Pradesh, India (including operational bases in Martur, Bapatla District, and Darsi, Prakasam District), JPS Box Homes integrates precision cold-formed profile roll-forming, automated MIG/MAG welding jigs, and automated sandwich panel lamination lines under strict ISO 9001 and ISO 14001 quality management parameters.
Engineering Benchmark: Unlike commercial trading intermediaries, every JPS Box Homes modular cabin undergoes factory jig alignment, ensuring frame squareness tolerances within ±1.5 mm and zero site re-drilling during field installation.
Our operational integrity and manufacturing standardizations are driven by an experienced corporate engineering and management team:
Directs corporate growth strategies, factory infrastructure scale, and international compliance standards.
Oversees steel procurement, automated fabrication schedules, and factory quality assurance checkpoints.
Leads structural load calculations, wind/seismic resistance validation, and assembly detailing.
Manages institutional partnerships, legal governance, and global supply chain logistics.
Achieving compliance under the European Construction Products Regulation (CPR No 305/2011) and securing authentic CE Certification (EN 1090-1 Structural Steel Execution Class EXC2) requires rigorous metallurgical and thermal performance control. CE-marked container cabins from JPS Box Homes adhere to standard structural design criteria to prevent deflection, envelope degradation, and moisture intrusion under harsh ambient conditions.
The core structural integrity of our modular cabins relies on cold-rolled high-tensile structural steel profiles (Q235B / Q355B grades). Corner columns are press-formed with integral multi-hole corner fittings complying with ISO 1161 dimensions, allowing secure twist-lock rigging during transport and multi-story stacking.
| Structural Component | Material Specification | Factory Coating Protection | Performance Standard |
|---|---|---|---|
| Corner Columns (4 Position) | 3.0mm – 4.0mm Q355B Cold-Formed Steel | Hot-Dip Galvanized + 120μm Epoxy Primer | EN 1090-1 Structural Load Bearing |
| Roof Main Beams | 2.5mm – 3.0mm Structural Steel Channel | Z275 Zinc Coating (275 g/m²) | Supports 1.5 kN/m² Uniform Snow Load |
| Floor Joist System | 2.0mm Secondary C-Purlin Grid (400mm Centers) | Electro-Galvanized + Anticorrosive Topcoat | 2.5 kN/m² Live Load Capacity |
| Wall Panel Enclosure | 50mm – 100mm Mineral Rockwool / PU Core | 0.5mm Pre-painted Galvanized Steel (PPGI) | EN 13501-1 Class A1 Fire Reaction |
Thermal bridging is a persistent failure point in low-grade container modifications. JPS Box Homes resolves thermal transmission using continuous tongue-and-groove joint profiles backed by closed-cell thermal gaskets. Depending on destination climate requirements, insulation cores are configured as follows:
Density: 100-120 kg/m³. Non-combustible Class A1 fire rating. Ideal for high-density workforce accommodation, industrial sites, and strict urban building codes.
Thermal conductivity: λ = 0.022 W/m·K. Provides superior U-values (down to 0.21 W/m²K at 100mm thickness) for sub-zero climates and low-energy cabins.
Density: 16-20 kg/m³. Lightweight thermal protection designed for standard site offices, mild weather zones, and short-term temporary installations.
The global modular construction landscape is undergoing a structural transition. Simple retrofitted shipping containers are being rapidly replaced by purpose-engineered, demountable container cabins manufactured on dedicated assembly lines. Key engineering innovations defining the sector include:
For seaside and heavy industrial applications, single-layer paints fail rapidly. Advanced factories apply a multi-tier coating regimen: hot-dip zinc plating (Z275 g/m²), followed by a 2-pack zinc-rich epoxy primer (60μm), and finished with a weather-resistant polyurethane topcoat (60μm). This system passes 1,500-hour salt spray testing per ISO 12944-6 standards.
Design for Manufacture and Assembly (DfMA) enables 100% digital pre-construction alignment. Utilizing structural BIM (Building Information Modeling) platforms, every structural hole, electrical conduit, and window reveal is pre-punched during cold-rolling, eliminating manual cuts and site assembly errors.
Modern container cabins are increasingly built with factory-integrated micro-grids. Top roof frame rails feature recessed mounting brackets for structural photovoltaic panels, paired with low-gwp heat recovery ventilation (HRV) units and integrated greywater loops for remote off-grid operation.
Sea freight rates dictate project viability. Modern flat-pack and detachable container designs allow up to 8 fully insulated 20ft cabin kits to nest inside a single 40ft High Cube (40HQ) ocean container, reducing shipping costs per unit by up to 75% compared to rigid converted ISO containers.
As main contractors, project procurement directors, and government buyers source modular space solutions, purchasing parameters are shifting from initial unit purchase price toward comprehensive life-cycle value analysis. Procurement teams must account for four major trends when evaluating CE-certified manufacturers:
Institutional buyers across Europe, North America, and Australia now require environmental product declarations (EPD) for prefabricated structures. Modern factories minimize embodied carbon through zero-waste cold-roll steel forming and recyclable mineral rockwool cores. Dry modular construction reduces site water consumption to zero and cuts total site carbon emissions by 60% compared to cast-in-place concrete.
While low-cost uncertified cabins feature cheaper initial prices, higher corrosion degradation, seal failure, and high thermal leakage drastically raise operational costs. Procurement managers are adopting 15-year TCO evaluations: high-specification cabins equipped with PIR cores and double-glazed low-E curtain walls save up to 45% on annual HVAC energy usage.
For rental fleets, infrastructure works, and temporary mining camps, a cabin's structural structural life across multiple disassembly cycles dictates return on investment (ROI). Bolted detachable cabins engineered with reinforced corner castings allow up to 10 complete erection-dismantling cycles without frame distortion or loss of structural integrity.
Customs authorities and municipal building inspectors are actively cracking down on non-compliant prefabricated imports. Overseas buyers require direct mill test certificates (MTC), structural calculation reports signed by certified structural engineers, and verified EN 1090-1 factory production control (FPC) audit documentation prior to contract signing.
JPS Box Homes bridges the gap between customized structural engineering and high-volume factory production. Our production infrastructure addresses the primary friction points encountered during overseas modular procurement:
Every batch of steel coil, sandwich panel, and structural hardware comes with full traceability and Mill Test Certificates meeting international structural standards.
From single 10ft security kiosks to multi-story 1,000-man accommodation camps with integrated sanitary blocks and glass commercial facades.
Engineered shipping bundles with custom steel banding, corner protectors, and detailed container loading plans to ensure zero freight damage.
Orders ship with step-by-step 3D assembly sequence drawings, structural torque specifications, and electrical wiring schematics.
High-density rockwool core panels offer 120-minute structural fire endurance (REI120) meeting stringent municipal fire safety codes.
Direct technical support from our structural engineering division for custom load calculations, wind uplift ties, and foundation detailing.
Detailed technical answers to common questions asked by project engineers, procurement managers, and international buyers during cabin selection:
CE Certification under EN 1090-1 requires complete structural calculations verifying dead loads, live floor loads (min 2.5 kN/m²), roof snow loads (min 1.5 kN/m²), and lateral wind loads (up to 120 km/h). Structural weld seams must undergo Non-Destructive Testing (NDT), and primary cold-formed steel sections must carry full EN 10204 3.1 material traceability certificates.
A detachable container cabin features fully un-boltable corner posts, floor frames, and roof frames. Up to 8 disassembled units pack loose into a single 40HQ container, offering maximum ocean freight density. A flat-pack container cabin arrives with factory pre-assembled roof and floor frames stacked into a compact 4-in-1 ISO bundle, reducing site assembly labor to 4–6 man-hours per unit.
Single-story container cabins do not require continuous concrete footings. They can be installed on point foundations (concrete piers or ground screw piles) situated beneath the 4 primary corner posts. For two-story or multi-module combinations, a reinforced strip foundation or concrete plinth beam is required. JPS Box Homes provides exact point-load reaction data with shop drawings.
For strict urban building codes, mining workforce housing, and industrial plants, Mineral Rockwool Sandwich Panels (75mm–100mm, 120 kg/m³ density) must be specified. Rockwool is non-combustible (Class A1 rating) and withstands temperatures exceeding 1,000°C without producing toxic fumes, providing up to 2 hours of structural fire barrier integrity.
Yes. Standard JPS Box Homes detachable and flat-pack modules feature structural corner columns engineered to support up to 3-story (G+2) unassisted vertical stacking. For higher story counts or heavy seismic zones, external structural steel framing bracing is integrated into the structural layout.
