Both the K1-K10 modular structure tent range and the W1 warehouse tent are clear-span aluminum buildings with 6061-T6 / 6082-T6 frames and 850 g/m2 PVC roofing. The choice between them is decided by four measurable points: maximum clear span (K1-K10: 3 m to 80 m; W1: 3 m to 60 m), length logic (K1-K10: unlimited length, extendable in 5 m bays; W1: customizable, typically 10 m to 100 m+), height geometry (K1-K10: eave height 2.5 m to 8 m; W1: peak height around 9 m at a 30 m span), and the wind and snow loads the site must carry (K1-K10: up to 140 km/h and 0.5 kN/m2; W1: up to 120 km/h certified and 75 kg/m2 configurable).

Where the K1-K10 vs W1 Decision Actually Goes Wrong

Most structure tent specification errors are not pricing errors. They are envelope errors: a project is matched to the wrong product family because one of four variables was assumed rather than checked.

Span ceiling. A project that needs 65 m to 80 m of column-free width sits inside the K1-K10 range of 3 m to 80 m but outside the W1 range of 3 m to 60 m. Changing family after the layout is drawn means re-engineering the frame, not re-pricing it.

Length logic. The K1-K10 series is designed to extend in 5 m bays with no published length limit, which suits phased expansion. The W1 is described as customizable in length, typically 10 m to 100 m+. A buyer who needs to add 25 m of storage in two years should confirm which length logic the supplier actually builds to.

Height definition. Eave height and peak height are not interchangeable. The K1-K10 data sheet publishes an eave height of 2.5 m to 8 m (customizable), while the W1 data sheet publishes a peak height of approximately 9 m at a 30 m span, with a span-to-peak ratio of roughly 1:3. Clearance for racking, cranes, hangar doors or grandstands depends on the correct number being used at the right point of the structure.

Load path and certification. K1-K10 structures publish wind resistance up to 140 km/h (customizable) and snow load up to 0.5 kN/m2. The W1 publishes wind load up to 120 km/h (certified) and snow load up to 75 kg/m2 (configurable). Load figures are configuration-dependent, so they are decision inputs, not marketing headlines.

Industry Background: Aluminum Clear-Span Structures in Industrial and Event Use

Demand for aluminum clear-span structures sits at the intersection of two markets that are both growing in the same direction. China exported approximately USD 3.11 billion of tents, awnings and sails in 2024 and holds a 53.3% share of that global trade, according to the Observatory of Economic Complexity. The wider global tent market, including industrial storage, sports and event applications, is projected to grow from USD 4.01 billion in 2025 to USD 6.07 billion by 2033, a CAGR in the 5-7% range.

Two regulatory layers sit behind these numbers. In the European Union, temporary structures with a ground area exceeding 50 m2 must comply with EN 13782:2015, which addresses structural stability under wind and snow loads. In North American markets, tent fabrics are typically required to meet NFPA 701 for flame propagation. KENTEN Structures states that its structures are produced and certified to IBC 2024, CBC 2025, ASCE 7-22, GB 50429 and EN 13782, and the K1-K10 range additionally publishes flame retardant ratings of DIN 4102 B1, M2 and NFPA 701.

The practical consequence for buyers is that span, load and standards compliance should be settled before finish and comfort options. Both product families use the same aluminum alloy grades and the same 850 g/m2 roof membrane weight, so the difference is not material quality. It is geometry, length behaviour, load configuration and sidewall strategy.

• Certification listed: ISO 9001, ISO 14001, ISO 45001.

Five Decision Rules That Resolve Most Projects

1. Above 60 m clear span: select the K1-K10 range; the W1 span range ends at 60 m.
2. Continuous length beyond the typical run, or planned incremental expansion: the K1-K10 range extends in 5 m bays with unlimited length.
3. Interior clearance governed by eave height: use the K1-K10 eave range of 2.5 m to 8 m rather than assuming a peak height figure.
4. Snow load configured beyond 0.5 kN/m2: the W1 data sheet explicitly states a configurable snow load up to 75 kg/m2, so storage projects in snow regions should be checked against the W1 configuration.
5. Steel or insulated sidewalls for storage: the W1 offers corrugated steel and sandwich panel side walls, which matches logistics and factory environments.

Step-by-Step: Matching Specifications to a Project

The sequence below turns the two data sheets into a single build brief. It follows the order in which the numbers interact, because changing span after sidewalls are chosen invalidates the load design.

1. Define the required clear span. Establish the widest uninterrupted interior dimension. If it exceeds 60 m, the W1 range is excluded automatically and the K1-K10 series (3 m to 80 m) is the applicable family.
2. Set the length logic. Ask whether the building must grow later. The K1-K10 answer is unlimited length in 5 m bays; the W1 answer is a customizable run typically between 10 m and 100 m+.
3. Confirm the height definition. Record eave height for racking and door openings (K1-K10: 2.5 m to 8 m customizable) and peak height for internal volume (W1: around 9 m at a 30 m span, ratio roughly 1:3).
4. Verify wind and snow loads for the site. Compare the site requirement against the K1-K10 figures of up to 140 km/h and 0.5 kN/m2, or the W1 figures of up to 120 km/h certified and 75 kg/m2 configurable. For EU projects above 50 m2, confirm EN 13782:2015 compliance; for North American fabric, confirm NFPA 701.
5. Choose sidewalls and foundation together. K1-K10 sidewalls are PVC, glass wall, ABS wall or sandwich panel, installed on ground anchors or concrete ballast. W1 sidewalls are PVC, corrugated steel or sandwich panel, with concrete anchors or ground stakes depending on site conditions.
6. Confirm delivery and support before ordering. KENTEN Structures states a lead time of 30-45 days and a minimum order quantity of 1 unit, with 100% full inspection before shipment plus raw material incoming inspection, OEM/ODM customization, and 24/7 remote technical support with spare parts supply and on-site installation guidance.

Use Cases: Which Family Fits Which Project

Project type, not price, is the fastest filter. The table below maps verified product and project facts to typical buyer scenarios.

Two delivery records show how far the K1-K10 platform has been pushed in practice. KENTEN supplied A-shaped structure tents and pagoda tents for the 2008 Beijing Olympic Games under a 50-unit programme covering security inspection channels, audience rest areas, VIP reception areas, media service points and operation management areas. For the 2022 Beijing Winter Olympic Games, a further 50 units of A-structure and double-decker tents served as security checkpoints, staff offices, dining areas, meeting rooms and command centres. In Kuwait, a single-unit pyramid structure exhibition hall delivered a 100% column-free interior for exhibition use.

Specification Comparison: K1-K10 vs W1

The table below uses only published product data. Where a value is not published in the product data for a family, it is marked as not published rather than estimated.

How to Read the Table as a Buyer

The K1-K10 advantage is envelope flexibility: wider span, unlimited extendable length, a broader sidewall palette including glass and ABS, and a higher published wind resistance. The W1 advantage is storage-specific configuration: a defined peak height ratio for volumetric interiors, steel and insulated panel sidewall options, and a snow load figure that is published as configurable to 75 kg/m2. A project that needs both attributes, such as a large-span industrial building with insulated walls, is normally resolved by specifying the wider family and configuring the sidewall system, rather than by stretching the narrower range past its published limits.

Frequently Asked Questions

Conclusion: Match the Envelope, Then the Finish

The K1-K10 modular structure tent range and the W1 warehouse tent are not competing versions of the same product. They are two envelopes built on the same aluminum frame discipline. Choose the K1-K10 range when the project needs a clear span beyond 60 m, unlimited length in 5 m bays, eave heights up to 8 m, glass or ABS sidewalls, or wind resistance configurable to 140 km/h. Choose the W1 when the project is storage-led, requires a peak height ratio of roughly 1:3 at a 30 m span, needs corrugated steel or sandwich panel side walls, and must configure snow load up to 75 kg/m2 for a logistics or manufacturing site.

Settle span, length logic, height definition and load configuration first. Sidewalls, colours and interior fit-out are then a straightforward follow-on decision, whether the project is a distribution centre, an exhibition hall, a sports facility or a multi-venue public programme.
