Metal Frame Structures

Metal Frame Structures

Металло-каркасные сооружения, в отличие от воздухоопорных имеют жесткую пространственную структуру, основанную на стальном или алюминиевом каркасе.

Каркас представляет собой систему, состоящую из арок трубчатой конструкции, опирающихся на столбчатый железобетонный фундамент, при этом форма арок может быть различна и зависит от архитектурного решения. Каркас обтянут тентовым покрытием, которое может иметь один или несколько слоев материала. Для климата средней полосы России, имея в виду зимнюю эксплуатацию сооружения, лучше применять многослойные покрытия с утеплителем.

Metal Frame Structures 

Company Arsenal-NT has great experience to offer best on the market prefabricated steel halls. We successfully joined our advanced fabric technology with high quality steel frame.

 Benefits of Duol prefabricated steel structure:

+ Best on the market membrane technology: Over 22 years experiences in air domes and membrane technology. More than 1100 fabric covered objects all over the world (Europe, Asia, Africa, and S. America). 

+ Easy maintenance: Our innovative lacquering film features exceptional self-cleaning properties, UV stability and long durability. 

+ Naturally Bright: DUOL translucent fabric increases the natural 

light within the prefabricated hall. This reduce or eliminate the need for lights to be turned on during daylight hours.

+ Quick to assemble: Thanks to easy assembling features, Duol prefabricated halls require less construction time, saving you with workers and machinery installation costs

+ More Foundation Options:  There are more types of foundations options available to suit your project need


+ Easily Relocated: DUOL prefabricated hall is designed to be permanent, but can be quickly disassembled or relocated.


+ Reliable supplier: Support all over the world. 100% efficient and fast after sale support - immediate technical support for clients, through mobile or email communication;  fly interventions of Duol technicians can be organized in very short time.

Duol DMSTM membrane technology 

Duol custom-designed PVC coated fabric comes with innovative lacquering film for best UV and high range temperature resistance. Duol new generation DMSTM membrane technology offers 

best on the market performance, durability and thermal insulation.

DUOL DMSTM is unique solution of double membrane system which guarantees resistance to harsh climatic conditions and ensure the highest temperature isolation.

DMSTM comes with more variants. Standard DMSTM provides thermal insulation of 3.05 W/m2K, while DMS PlusTM provides thermal insulation down to 1.74 W/m2K and E-DMS PlusTM down to 1.43 W/m2K (measured by  independent test institute).

DMSTMthermo (Double membrane system without thermal bridges) is available for insulation.

DUOL double membrane system is composed by two layers of the membrane is stronger, made by high tenacity polyester fabric, and protected with special lacquering, holding all the forces, while the inner membrane is insulating one and lighter. Every ca. 2.5m there is HF welding, where four membranes are overlapping and are welded together, presenting the strong reinforcement in vertical and horizontal direction.

Fabric halls for industry, logistics and other commercial purposes

 Whether you need hall for storage, logistics or for manufacturing area, Duol portable fabric buildings are a quick and cost-effective solution for different industrial operations. The fabric building has no central support, so trucks and lifts can easily operate in any direction and high side wall clearance allows maximum utility.






Duol fabric building creates a bright, spacious, safe and comfortable work environment for your employees. With little or no artificial daytime lighting required, these fabric buildings are designed and engineered to adapt to heavy industrial use, with many available options such as exhaust vents for fumes, or extra hot dipped galvanization for corrosive environments.






Duol fabric buildings have unparalleled engineering and design capability to provide customized solutions to complex project needs including high wall buildings and liftable buildings. They are ideal for use as a base during construction, for warehousing of vehicles, machinery and equipment, for bulk storage, on-site workshops...



Seizing unforeseen business opportunities is the key to any successful organization. A DUOL fabric building can easily be extended or dismantled and reinstalled in a new location.


 Conventional industrial buildings are expensive to build and maintain. DUOL fabric building are a great alternative and can be built for a fraction of the cost, and time of conventional buildings. In addition, owners often pay lower property taxes.





  • Revolving doors

Revolving doors are specifically built to withstand the building pressure pushing in both  rections on the panels without fatigue failure. Brush seals minimize air losses whilst maintaining a mooth

operation. The doors include large glass panels in order to see other users and the housing is ade from maintenance free galvanized steel.


  • Pedestrian doors

Pedestrian doors are used mainly for handicapped people access, but are also useful for hand-truck deliveries. Two doors are built in a frame with a short connecting tunnel creating an airlock system, thereby maintaining the building pressure and minimizing air loss. The frame and doors are built from galvanized steel for long life and include glass windows for safety.

  • Emergency doors  

The purpose of this doors are to give providing emergency paths. The frame and the door leaf are made by galvanized metal construction. The doors have porthole, emergency exit signs and lights and meets fire and building codes.


  • Transport tunnel

Transport tunnel is an entrance for large vehicles and can be used also as a storage room for the equipment.

 Waste or Decontamination hall 

We use the highest quality steel tubing, so these buildings are made to last and will hold up strong in corrosive environments.

There are no internal support columns to interfere with forklifts, balers, skid loaders, conveyers and other heavy machinery. With so many customizable options, Arsenal-NT has the perfect solution for your waste management or decontamination building.






Arsenal-NT standard series

Duol GS series

GS series is classical shape with free interior space and many combinations possibilities.

A hall suited for various activities from company and private use, to trade shows and exhibitions, sport, cultural events, over industrial purposes like storage space, workshops, … to sport applications like covering for tennis courts, swimming pools, … in short - ideal solution.



Duol DS series

DS series are pre-engineered arch-shape fabric structures with a steel truss frame and standard clear span widths up to 50m wide.

The truss system is designed with shipping in mind and ease of installation. Truss sections fit onto standard flat bed trucks or into shipping containers with ease and the entire sections bolt together to form the structural framing system.

The combination of the framing and proprietary fabric panel tension system creates speed of installation advantages while the design of the DS series as a permanent or semi-permanent application has the potential to be completely relocatable to another location, saving 99% of your purchased material.




Custom made fabric structures

Besides standard series, Arsenal-NT can design and construct also wide range of custom made structures. We focus on the needs of the customer at all times. Special requirements vary from extra high side walls, large doors to extra ventilation openings.
