HEE
Our marine expansion plate is a critical outfitting component for marine piping support systems. A concave curved saddle groove is cold pressed directly into the steel plate. The arc profile matches the outer diameter of steel pipes. This special curved profile provides elastic deformation allowance to absorb thermal expansion and contraction displacement of pipes, releasing thermal stress while bearing pipe weight. It prevents pipe cracking and bracket damage caused by temperature change and vessel vibration at sea. Compared with conventional pipe shoe (flat base + separate corner plate), this integrated expansion plate reduces on-site welding work, cuts weld quantity and lowers NDT inspection scope. It is widely installed on vessel decks, engine rooms, ballast tanks and fuel oil tanks for ballast pipes, seawater pipes, fuel oil pipes and fresh water mains. Suitable for new shipbuilding, ship repair and offshore platform piping projects.
Barge Deck Protection: Install on deck sides, bow and stern contact zones to withstand continuous impact from tugboat pushing operations.
Impact Load Dispersion: The arched geometry transfers concentrated point impact into distributed force across the plate, protecting the base deck structure from collapse and tearing.
Widely adopted for inland barges, coastal barges, pontoons, storage barges, sand‑transport barges and various other working vessels.
Acts as a cost‑saving alternative to full deck thickening, featuring convenient on‑board replacement and routine maintenance.
✅ Produced directly in our own factory, strict quality control throughout the whole production process, competitive factory price without middlemen.
✅ One‑piece stamping construction with no split welds, delivering outstanding impact resistance.
✅ Optimized arched mechanical design for reliable anti‑deformation performance under heavy loads.
✅ Marine‑grade anti‑corrosion paint coating, well adapted to humid and salt‑spray marine working conditions.
✅ Full‑range custom service available. Length, width, plate thickness, arch height, curvature and surface treatment can all be tailor‑made according to your drawings or samples.
✅ Multiple material selections including Q235B carbon steel and AH36 marine steel to match different vessel project requirements.
✅ Bulk‑order capacity, we can handle large‑volume orders for shipyards and marine project contractors.

EXPANSION PLATE
Our barge arched anti‑collision plates are fully manufactured in our own factory, integrally stamped from complete marine steel sheets. Without segmented welding joints, the plates maintain stable and reliable mechanical performance.
Barges are exposed to frequent collisions during daily operation, mainly from tug pushing and berthing against adjacent vessels. Ordinary bare deck plates are prone to permanent denting and cracking after repeated heavy impact. Weld this arched wear‑resistant plate onto high‑stress deck zones. Its curved profile efficiently spreads impact energy and safeguards the original base deck structure, which greatly reduces vessel maintenance frequency and repair costs.
Every product is finished with professional marine anti‑corrosive paint to cope with corrosive inland water and coastal environments. As an original manufacturer, we focus on custom‑built marine steel components. All key parameters including dimension, arch curvature, plate thickness and material grade can be adjusted to fit your unique barge design.
Whether you need small batches for repair work or large‑volume supply for new‑build barges, our factory can meet your production demands. Please send us your technical drawings and specifications to get your custom quotation.
