Pros and Cons

Glass

Toughened glass

The strength is several times higher than that of ordinary glass, the fragile property is improved, and the resistance to rapid cold and heat is higher than that of ordinary glass.

Normal Glass

The light transmittance of ordinary glass is good, and its surface is smoother than tempered glass, but its strength and safety are worse than that of toughened glass.

Window frame and seat

Q235

Good welding performance, Good low temperature toughness

LF5 Aluminum

Anti-corrosion, but expensive and not fireproof

Copper

Excellent rustproof performance but the strength is lower than steel and aluminum

Seal

Neoprene

Excellent Watertight performance

Toughened Glass

The strength is several times higher than that of ordinary glass, the fragile property is improved, and the resistance to rapid cold and heat is higher than that of ordinary glass.

Electric heating glass

The electric heating glass has the function of defrosting frost, and it can defog and defrost after power on. There is also good light transmission to ensure the cab visibility. Laminated glass is tempered glass with high hardness and is not easy to break. With anti-ultraviolet function, reduce the damage of ultraviolet rays to the driver.

Other manufacturer’s low quality marine wheelhouse fixed rectangular window

HI-SEA high quality marine wheelhouse fixed rectangular window

1. The glass cuts corners, adopts non-tempered glass, and the glass thickness is thin, the structure is fragile and fragile, and the sharp edge after rupture has caused harm to the human body.

2. The window frame adopts the metal structure with high impurity content, the cost is low, and the strength is not up to standard.

3. The window edge sealing material has poor ductility, is easy to deform, and cannot guarantee watertightness.

4. Improper surface treatment of castings and defects such as cracks and pores will affect the service life of portholes.

5. The light transmittance of the glass is poor, which affects the field of vision, and the electric heating glass is not equipped with overheat protection device, which is easy to cause safety hidden danger.

1. The glass adopts a multi-layer tempered glass structure, which not only has high strength, but also better safety, and has a certain sound insulation function.

2. The material standard refers to CB/T 3226-1995, which conforms to the marine specification

3. After the parts are processed, anti-rust treatment such as hot-dip galvanizing or anodizing is performed.

4. The window shall be impacted by water with a pressure of not less than 0.2MPa and there shall be no water droplets on the impacted part.

5.

5. All inspection items for portholes are in compliance with the requirements.
