Our Marine Rose Box, also known as Strum Box, is a marine suction strainer installed on the inlet of ship pumps. It adopts perforated metal plate structure to intercept sand, seaweed and solid debris in seawater, effectively preventing pump blockage and damage. We supply round and square rose boxes with multiple material options: carbon steel plate, stainless steel and brass. 

Brass: Resistant to seawater corrosion, suitable for medium and small-sized diameters and scenarios with high rust prevention requirements.

Stainless Steel: Suitable for harsh seawater environments and long service life requirements.

Carbon Steel: Low cost, suitable for general ship applications, usually requiring galvanization.

The square type is equipped with lifting lugs for easy installation and maintenance. Our marine rose boxes can be supplied with manufacturer certificates, and we support OEM customization including size, logo and special requirements for ship projects. Widely used for bilge system, ballast system and other seawater piping systems on vessels.

Compared with ordinary suction filters, our marine rose box features strong corrosion resistance, robust construction and long service life. Brass rose boxes perform well in saltwater and anti-rust scenarios. Stainless steel models are ideal for harsh seawater environments. Carbon steel types offer cost-effective solutions for general marine applications.
