Frequently Asked Questions

Answers to common questions about prefab houses, container houses, steel structures, modular buildings, shipping, installation and more.

Q

How long does prefab house production take?

A

Production lead time varies by product type and order size. Standard container house units typically take 15-25 days for production. Prefab panel houses take 20-30 days. Steel structure buildings typically require 25-40 days. Large camp projects with multiple buildings may take 40-60 days. We confirm exact timelines during the quotation process based on your specific project requirements.

Q

Can you provide installation guidance?

A

Yes. Every prefab building supply includes detailed installation documentation with illustrated assembly guides. For container units, we provide placement and connection instructions. For panelized and modular buildings, we provide step-by-step erection manuals. For larger projects, we can arrange remote technical supervision or on-site installation supervision — please discuss your needs during the quotation stage.

Q

Do I need to provide a layout or floor plan?

A

Not necessarily. If you have a layout or floor plan, it helps us give you the most accurate quotation and ensures we supply the correct configuration. However, if you do not have drawings yet, we can work from your requirements — such as the number of people to accommodate, intended use, site dimensions, and budget — to propose an appropriate layout. Send us whatever information you have and we will help you develop the right solution.

Q

How are prefab houses shipped overseas?

A

Shipping method depends on the product type. Container houses are shipped as fully assembled units inside standard 20ft or 40ft shipping containers. Prefab panel houses and modular buildings are typically shipped in knocked-down (CKD) or flat-pack format to maximize container efficiency — often 4-8 units per 40ft container. Steel structure buildings are shipped as prefabricated structural components. We handle all shipping coordination from our facility in Foshan, China to your designated port.

Q

Can the house design be customized?

A

Yes. All our prefab buildings can be customized. For container houses, we can modify internal layouts, electrical fit-out, doors and windows, and exterior finishes. For panelized and modular buildings, we offer customization of dimensions, layout configuration, insulation levels, wall and roof finishes, and utility systems. Steel structure buildings are essentially custom-designed per project requirements. Contact us with your specific requirements and our team will provide options.

Q

What information is needed for a quotation?

A

For an accurate quotation, it helps to provide: (1) Product type or category you are interested in; (2) Intended use and any specific requirements; (3) Project location and site conditions; (4) Required quantity or floor area; (5) Target budget range if available; (6) Project timeline — when you need delivery; (7) Layout or floor plan if available; (8) Any special requirements such as extreme climate conditions, fire ratings, or specific certifications. Even partial information is useful — we can ask clarifying questions during the quotation process.

Q

What is the typical installation time on site?

A

Installation times vary by product and project size. A single 20ft container house can be placed and made operational within 1-2 days. A single prefab panel house unit typically takes 3-7 days to erect and make weather-tight. A steel structure warehouse of 3,000sqm typically takes 20-40 days to erect and fully close in. Large camp projects with multiple buildings may require 45-90 days for full installation and commissioning. Complex projects with multiple building types are coordinated as a phased installation program.

Q

What payment methods do you accept?

A

Standard payment terms for overseas projects are 30% deposit to confirm order, 70% balance payment before shipment. We accept T/T bank transfer as the primary payment method. For larger projects, we can discuss payment milestone structures that align with production and shipping milestones. We do not accept credit card payments for large orders. All payment terms are confirmed in the formal Sales Contract before production begins.

Q

How is the foundation prepared for prefab houses?

A

Foundation requirements vary by product type. Container houses require a relatively simple level concrete pad or beam foundation — essentially a flat, level surface capable of supporting the load. Prefab panel and modular buildings typically require either a strip foundation or a concrete slab, depending on building size and site soil conditions. Steel structure buildings require proper foundation design based on structural loads and site soil conditions — this is usually addressed in the project-specific engineering design. We provide foundation design recommendations and bearing capacity requirements as part of the project documentation package.

Q

What after-sales support do you provide?

A

We provide documentation support including installation manuals, electrical and plumbing schematics, maintenance guidelines, and spare parts lists. For projects with our technical supervision service, our engineers are available for remote consultation during and after installation. We maintain a spare parts inventory for common components and can ship replacement parts as needed. For structural issues, we provide engineering assessment and remediation guidance. We do not provide on-site maintenance services internationally but can coordinate with local contractors if needed.

Q

What is the difference between flat pack and fully assembled container houses?

A

Flat pack container houses are shipped in knocked-down kit form — all structural panels, flooring, and fittings are packed flat into containers, maximizing shipping efficiency (up to 4-6 units per 40ft container). Assembly requires labor and basic tools on site. Fully assembled container houses are built in our factory, tested, and shipped inside standard shipping containers. They arrive ready to place and connect to utilities. Flat pack is more cost-effective for shipping but requires assembly labor. Fully assembled is faster to deploy but has higher shipping costs.

Q

What certifications do your prefab buildings have?

A

Our manufacturing facility operates under quality management system processes. Specific product certifications vary by destination market and product type — common certifications include structural design certification, fire rating documentation, and material specifications. If your project requires specific certifications or compliance documentation, please inform us during the quotation stage so we can confirm availability and provide appropriate documentation. Engineering calculations and material certificates can be provided for most products and structural configurations.

Q

Can prefab buildings be used in extreme climates?

A

Yes. We have experience supplying buildings for extreme climate zones including hot desert climates, tropical humid regions, cold temperate zones, and high-altitude sites. For extreme climate applications, we specify appropriate insulation levels, ventilation strategies, HVAC systems, and structural design parameters. Desert applications require enhanced roof insulation and ventilation design. Cold climate applications require high insulation values and proper condensation management. Please inform us of your site climate conditions during quotation so we can specify the appropriate configuration.

Q

What is the lifespan of prefab buildings?

A

Lifespan varies by product type and usage conditions. Steel frame container houses properly maintained can last 15-25 years. Prefab panel buildings with standard specifications typically have a design life of 20-30 years. Steel structure buildings are designed for 50+ year structural life. Light steel villas with permanent construction quality are designed for 50+ years. Actual lifespan depends on maintenance, environmental conditions, and usage intensity. We provide maintenance guidelines to maximize building lifespan.

Q

How do you handle customs and import clearance?

A

We work with experienced freight forwarders who handle export documentation from China. For your import, you will need a reliable customs broker in the destination country to handle import clearance, duties, and any local certifications. We provide detailed packing lists, commercial invoices, and Bill of Lading documents. If your country has specific import requirements for prefabricated buildings, please inform us during quotation so we can prepare accordingly and confirm that our products can meet those requirements.

Q

Can your buildings be combined or expanded?

A

Yes. Many of our products are designed for combination and expansion. Container houses can be connected side-by-side or stacked using our linking通道 and stacking connection kits. Modular office buildings can be connected to create larger complexes. Steel structure buildings can be designed with future expansion in mind — such as additional bays or mezzanine floors. If you anticipate future expansion needs, discuss this during the design stage so we can incorporate connection provisions into the initial supply.

Q

Do you offer site surveys or feasibility assessments?

A

We do not typically conduct physical site visits for overseas projects due to cost and logistics. However, we provide detailed site requirement questionnaires to gather information about site conditions, access constraints, climate, and local infrastructure. From this information, we can assess feasibility and identify any site-specific challenges. For complex projects, we recommend engaging a local structural engineer to assess foundation conditions. Our technical team is available for video calls to review site photos and discuss conditions.

Q

What is included in the standard delivery scope?

A

Standard delivery scope includes the structural building components, all required hardware and fasteners, installation documentation, and typically one set of spare parts. For container houses, standard scope includes the container shell with basic electrical distribution andLighting. For prefab panel buildings, standard scope includes all structural panels, roof system, doors, windows, and basic electrical conduit. Detailed delivery scope is confirmed in the quotation document for each project. Optional additions include furniture packages, premium finishes, extended electrical fit-out, and HVAC systems — please specify your requirements.

Q

Can we visit your factory before placing an order?

A

Yes, we welcome factory visits by serious prospective clients. Our manufacturing facility is located in Foshan, Guangdong Province, China. We can arrange factory tours to show our production processes, quality control procedures, and completed product displays. We can also arrange visits to completed project sites in China if appropriate projects are available. Please contact us to schedule a visit at least 2 weeks in advance. We can assist with airport transfer arrangements from Guangzhou Baiyun International Airport.

Q

What languages do you communicate in?

A

Our primary business language is English. We communicate with overseas clients exclusively in English — including quotations, technical discussions, contracts, and documentation. Some team members also communicate in Chinese. All technical documentation, installation manuals, and drawings are provided in English as standard. If you require documentation in additional languages, please discuss this during the quotation stage.
