China Sourcing | Boxx Modular - China Sourcing for Modular Buildings

Source Modular and Portable Buildings from China | Boxx Modular

Boxx Modular coordinates supplier matching and procurement for portable offices, classrooms, clinics and welfare buildings. Send the occupancy date, destination and site conditions so we can compare quotes with the same delivery and fit-out scope.

Four ways a portable building is usually specified

These cards are selection routes, not a catalog of finished SKUs. Live product names and photos load in the product grid.

Single-storey modular site office with steel skirt and access stairs

Site offices

Relocatable, one or two storeys

Classrooms

Swing space and training rooms

Modular clinic block with a plant deck and service riser

Clinics

MEP scope written room by room

Welfare and sanitary modules staged for transport

Welfare blocks

Sanitary packages and plant rooms

Four briefs you can use to compare suppliers

These illustrative RFQs show how the same four fields expose different cost and delivery risks. Quantities are scenario assumptions. Images illustrate the building types.

RFQ example · site offices

Gulf Coast fabrication yard

For a 48-module yard with a two-storey stack, request a separate allowance for stairs and set work. If a project engineer specifies 45 m/s, attach the exposure and enclosure assumptions and ask each bidder to identify its uplift reactions.

Building type: Volumetric offices
Country: United States
Quantity: 48 modules
Delivery scope: Design basis, factory fit-out, set plan

Sixteen classroom modules linked by a covered walkway

RFQ example · education

District swing classrooms

For a 16-room swing campus, compare PIR and mineral-wool wall options against the project’s U-value and fire strategy. Request a section at the covered link so the reviewer can assess the thermal bridge and accessible route.

Building type: Classroom modules
Country: United States
Quantity: 16 modules
Delivery scope: Envelope note, link corridor, set sequence

Clinic modules with a separate electrical skid

RFQ example · clinic

Remote clinic block

For eight clinical modules, mark the water, power and drainage termination points on a service drawing. Ask bidders to list what they preinstall and what needs field testing after connection to incoming utilities.

Building type: Clinic modules
Country: Canada
Quantity: 8 modules
Delivery scope: MEP boundary, sanitary package

Bolted knock-down office frames packed for a mining camp

RFQ example · camp offices

Mining camp offices

If the camp route limits full-height loads, ask for a bolted frame quote and a packed-unit drawing for the 40HQ. Compare actual stack height, gross load and assembly crew days before crediting a lower freight quote.

Building type: Bolted offices
Country: Australia
Quantity: 36 modules
Delivery scope: Container plan, torque log

Uses we sort before talking about price

Slide the row. Each use changes the load file, the interior package and the question of temporary classification versus a permanent code path.

Construction site modular office beside a tower crane

Construction yards

Short leases, repeat moves, and a foundation that may be timber pads rather than a slab.

Portable classroom beside an existing school wing

Education

Acoustic partitions, daylight, and an accessible route that a bare module does not include.

Modular medical intake room with a handwash station

Healthcare intake

Washable finishes and a clear split between factory sanitary fit-out and site medical gas.

Workforce dining module at a remote camp

Camp support

Dining, laundry and offices share a crane plan but not a fire strategy.

Two bedroom portable cabin on a rural lot

Small dwellings

A 2 bedroom portable building still needs a local energy and fire review if people sleep in it.

Questions that change the specification

Use, quantity, deployment country, plan size, number of storeys, design wind speed, ground snow load, seismic basis, interior scope, target occupancy week and destination port. A 14 foot modular office rental question and a purchase of a 16 by 40 portable building are different commercial paths, so say which one you mean.

No. Temporary classification can shorten a lease and allow a later move. It does not replace the fire, energy, accessibility or structural review required where the building will be occupied. Permanent modular construction (PMC) and a relocatable building (RB) can use similar modules and still follow different approval files.

A core datasheet is not a wall. Joints, doors, windows and penetrations have to sit in the same fire strategy. We ask for the system reference the project intends to use, and we do not describe a panel as fireproof.

We request the supplier’s documents for the quoted configuration. Have your local reviewer verify the design basis and permit path. A supplier’s ISO 9001 scope covers a management system. Ask separately for the applicable structural and assembly evidence.

A volumetric box leaves the factory with more of the interior complete and needs a crane plus a road envelope close to 6055 × 2435 × 2896 mm for a common office module. A bolted frame packs denser, often in the 4–8 units per 40HQ range for knock-down kits, and it asks the site crew to close the joints. Neither choice is universal. The Building Selector lays the trade-off out by use and climate.

Tell us the country, the headcount and the week you need people inside. We reply with the building system that fits those limits, or we say when a module is the wrong tool.
