Heavy Composite
Manufactured under stringent ISO 9001 and CE execution classes, our composite floor decks, magnesium boards, and structural claddings deliver unyielding dimensional stability under dynamic load cycles and harsh freeze-thaw exposure.
In high-density Moscow developments, civil contractors operate under stringent Russian structural norms. Sourcing structural decking from China demands uncompromising compliance with local limit state design methods, fire classification criteria, and sub-zero yield requirements.

From the freezing winter logistics corridors of the Central Ring Road (TsKAD) to the architectural towers of Moscow City, our structural decking panels solve acute regional construction dilemmas.
Class-A distribution parks in Domodedovo, Podolsk, and Noginsk demand long continuous spans and rapid concrete pours without temporary shoring props.
Multi-story steel framed construction across Moscow commercial clusters requires lightweight composite slabs to curtail crane lifting loads and deadweight.
Heavy refrigeration complexes in Dmitrov and Stupino require decking skins that remain dimensionally stable and impervious to internal condensation.
High-traffic pedestrian transit hubs (TPU) and open-air railway platforms subjected to aggressive chemical salting and continuous vibration.
An authoritative analysis of shifts in structural engineering, import substitution, and supply-chain reconfiguration following European trade realignment.
The withdrawal of Western European metal decking fabricators (e.g., Tata Steel, Ruukki, Kingspan) created an acute demand for direct tier-1 Chinese manufacturers with autonomous engineering labs. Russian general contractors (Генподрядчики) now insist on direct mill certificates, eliminates intermediary traders, and configure direct rail routes into Vorsino and Bely Rast terminals to maintain uncompromising construction cadences.
With Moscow's sub-zero winter temperatures running from November to late March, wet-pour concrete work entails massive heating costs (electro-heating wires, thermal tarpaulins). Progressive developers are shifting toward deep-ribbed structural metal decks and pre-engineered dry sub-flooring (such as high-density OSB-4 and non-combustible MgSO4 panels), slashing on-site wet curing requirements by over 45%.
Economic optimization of structural steel frames has prompted Russian design institutes to transition from traditional St3ps steel to higher strength classes like S350GD, S420GD, and 09G2S equivalents. Simultaneously, standard zinc coatings are being replaced by high-performance Zinc-Aluminum-Magnesium (ZM) alloy coatings, delivering up to three times greater corrosion protection in chloride-rich Moscow urban environments.
Operating a modernized, 85,000-square-meter manufacturing complex, our plant houses 14 high-speed multi-station cold roll-forming lines, automated decoiling, leveling, and computerized punching machines capable of delivering precise lengths up to 14.8 meters.
We source prime hot-dipped galvanized coil strictly from tier-1 steel mills (Baosteel, Shougang). Every batch undergo rigorous cold-bend tests, coating adhesion checks, and metallurgical grain assessments to guarantee ductile behavior and zero micro-cracking at extreme -50°C climatic exposures.

Practical answers addressing regulatory compliance, cross-border payments, customs clearance, and cold-climate structural performance.
Yes. Our galvanized structural decking profiles are engineered in compliance with GOST 24045-2016 (Profiled steel sheet for construction) and limit state calculation guidelines outlined in SP 260.1325800.2016 and SP 266.1325800.2016. We provide full chemical assay sheets, yield curve metrics, and section properties (moment of inertia Ix, section modulus Wx) to facilitate seamless approvals by Russian structural design institutes (ЦНИИСК им. В.А. Кучеренко).
Cold-brittle fracture is averted by utilizing low-carbon, micro-alloyed structural steel grades (equivalent to Russian 09G2S / European S350GD+Z). These coils maintain high Charpy V-notch impact energy at -40°C and -50°C. Furthermore, continuous cold roll-forming with calibrated bending radiuses ensures residual stress is minimized, preventing hairline micro-fissures in cold weather.
We offer direct containerized rail freight via the China-Europe Railway Express (CR Express) departing from major hubs (Zhengzhou, Xi'an, or Lianyungang) directly to key Moscow terminals including Vorsino (Ворсино), Silikatnaya (Силикатная), and Bely Rast (Белый Раст). Normal rail transit takes between 14 to 18 days. For oversized parcels, flat-rack multimodal ocean-rail via Vladivostok or Saint Petersburg is coordinated.
To eliminate currency exchange risk and Western banking frictions, we fully support direct cross-border trade settlements in Chinese Yuan (CNY / RMB) or Russian Rubles (RUB) through bilateral banking relationships (such as VTB Shanghai, Bank of China, and agricultural/commercial channels). Contracts can be executed under Incoterms 2020 CIP Moscow, DAP Moscow, or FOB Chinese ports.
Steel composite floor decking acts as non-combustible building material (Class NG / НГ under GOST 30244-94). For elevated fire endurance requirements (REI 60 to REI 120), our technical engineers supply load-bearing fire design charts specifying reinforcement mesh embedment depth and fire-retardant coating compatibility for consultant sign-off.
Absolutely. We manufacture every sheet to project-specific erection drawings (схемы раскладки настила) in custom lengths from 1,500 mm up to 14,800 mm. Custom cut-to-length sheets minimize site scrap, speed up installation on frozen job sites, and eliminate the need for thermal flame-cutting that damages zinc anti-corrosion layers.
Standard indoor dry applications utilize Z180 (180 g/m² combined both sides). However, for Moscow infrastructure exposed to harsh humidity and winter chemical salts, we supply heavy zinc Z275 (≥20 microns per side) or high-performance SuperDyma / Zinc-Aluminum-Magnesium (ZM200-ZM310) coatings, delivering up to 30 years of design service life without surface oxidation.
Yes. As a comprehensive structural envelope manufacturer, we deliver turn-key kits including ISO 13918 certified Nelson shear connectors, ceramic ferrules, galvanized perimeter pour stops (edge formwork flashings), closed-end profile metal closures, and heavy-duty structural self-drilling fasteners.
Whether you require composite floor decking for a Moscow City high-rise, deep-span roof decking for an e-commerce logistics hub in Noginsk, or non-combustible insulated floor boards, our technical engineering desk provides static analysis, BIM-compatible nesting drawings, and swift commercial quotes.
