Comparison Differences
Other manufacturer’s low quality marine fixed shutter
HI-SEA high quality marine fixed shutter
1. The shutter material is cut corners, the plate thickness is thinner, the window is more fragile, and the service life is short.
2. The surface of the louver, window frame, handle and other parts is uneven, the welding process is not good, there are burrs, sharp corners, etc.
3. The cover switch operation is inflexible.After the window is closed, there is no close fit between the cover plate and the shutter panel.
4. The shutter surface is not properly rust-proof and heat-resistant, so it is not resistant to corrosion and high temperature. Maintenance costs are high.
1. The glass shutters are made of high-quality Q235 steel and LF5 aluminum, the structure is sturdy and durable, and the service life is long
2. All parts of the shutter are processed with anti-rust treatment, and the surface is smooth and flat, and there are no defects such as bubbles and burrs that affect the strength of the shutter.
3. After the shutter is assembled, the opening and closing test is carried out. The opening is flexible, and the shutters are tightly fitted after closing, and the sealing performance is good.
4. Shutters are not only rust-proof but also high-temperature resistant, and are used in chimneys on ships.
