Large platforms can be assembled on-site in a matter of hours or days without the need of cutters or cranes, therefore, the labor and safety risks are greatly minimized thanks to the existence of standard quick-connect interfaces.
Embedding the core of the units with high-density polyurethane foam, in combination with the usage of up-to-date anti-corrosion coatings, the life of the units can be extended significantly up to 21 years. On top of that, the maintenance cost is permitted to stay at only 30% of that of the concrete alternatives, which are definitely both environment-friendly and economical.
It won’t take long before 1–5 meter diameter modules can freely combine with one another; thus, you can add more whenever you want, install mooring rings, fenders, sensors, solar mounts, or a monitoring system to meet the upgrades of the future.
The company has met the certification requirements of DNV GL marine, as well as the standards for aging resistance of ISO 17357, and quality management of ISO 9001, among others. This is like having a stamp of authority from various governments that you cannot refute and a simple inspection process for the product.
Shenyang Zhongda Steel Structure Co., Ltd. has been a national high-tech company since 2004. They are an 80,000 tons steel structure company supported by 120,000 m² modern factory, and automated production lines.
Having successfully delivered more than 60 flagship projects, we are recognized as a strategic partner to top-tier state-owned enterprises. The intricate and thorough procedures that we apply in major bridges like NDT, welding and stress analysis are presently being executed for every module of Aluminum Pontoons, thus ensuring the highest degree of durability on which you can always rely.
Size&Shape — The diameter is 300 to 800 mm, and 1 to 5 m capacity units are also made to order with length and cross-section being variable.
Buoyancy&Load Capacity — Polyurethane foam filling and ballast are perfectly chosen taking into account the crane tonnage, water depth, and load props.
Material&Coating — Initially, the steel Q235B can be used, but you can also choose the higher strength grades or marine-grade anti-corrosion layers which are more specialized.
Add-Ons — A simple list of items consists of mooring rings, fender systems, anchor points for the chain, sensors, solar brackets, etc.
Connection Types — Extremely fast bolt, clip, or hybrid connections for almost no-weld.
Finish&Branding — You can paint in any RAL color you want, and you may put your company logo or safety markings as well.
Special Features — DP positioning prep, ice-resistant design, eco-upgrades, and so on.
Also, the experts are involved directly from the initial to the final stage. On top of that, you will get a 3D model within 24 hours or less.
From 2 to 4-meter diameter modules with built-in fenders and mooring; the work platform was quickly assembled to allow working on several vessels at the same time and can be very easily reused.
International Ocean Festival Floating Venue — A large exhibition platform that can be quickly deployed, and after the event, it is dismantled very easily–high reuse, and low environmental impact.
