Durability and Strength:

Stainless steel Biminis are renowned for their exceptional durability and strength. They are less prone to corrosion and damage caused by exposure to harsh marine environments,
making them a preferred choice for boaters seeking long-lasting and robust solutions.

Resistance to Corrosion:

Stainless steel exhibits superior resistance to corrosion, making it an ideal choice for saltwater environments.
This corrosion resistance ensures that the Bimini maintains its structural integrity and appearance over an extended period, even in challenging maritime conditions.

Aesthetics and Shine:

Stainless steel Biminis boast a sleek and polished appearance, adding a touch of sophistication to the boat’s overall aesthetic.
The shiny finish of stainless steel can be an attractive feature for boaters looking to enhance the visual appeal of their vessel.

Maintenance and Cleaning:

Stainless steel is relatively easy to maintain and clean. It requires minimal effort to keep its shine and appearance intact.
This can be advantageous for boaters who prioritise low-maintenance accessories that still offer a polished and well-maintained look.

Heavier Duty Applications:

In situations where a heavier-duty Bimini is required, such as for larger boats or in areas with high winds, stainless steel Biminis are often preferred.
The inherent strength of stainless steel makes it suitable for heavy-duty applications where extra durability is crucial.

High-Temperature Resistance:

Stainless steel exhibits better resistance to high temperatures compared to anodised aluminum. This feature can be advantageous
in areas with intense sunlight or for boaters who regularly operate in hot climates.

Enhanced Stability:

The weight and density of stainless steel may contribute to enhanced stability in windy conditions. Boaters in areas prone
to gusty winds may appreciate the added stability provided by stainless steel Biminis.

Malleability for Customisation:

Stainless steel is malleable and allows for intricate designs and customisation. Boaters seeking a personalised touch or
specific design features may find stainless steel more accommodating for customisation.

Anodised Aluminium Biminis

Not to be outdone, there are some excellent characteristics and advantages of Anodised Biminis also.

Lightweight Construction:

Anodised aluminum is significantly lighter than stainless steel. Boaters looking to minimise overall boat weight or those with smaller vessels may prefer the lightweight nature of aluminum Biminis.

Corrosion Resistance:

While not as corrosion-resistant as stainless steel, anodised aluminum still offers great corrosion resistance. This makes it suitable for freshwater environments or areas with less severe salt exposure.

Ease of Installation:

Due to its lighter weight, anodised aluminum is often easier to handle during installation. Boaters who prioritize ease of setup or anticipate frequent removal and reinstallation may find aluminum Biminis more convenient.


Anodised aluminum Biminis are generally more cost-effective than their stainless steel counterparts. Boaters on a budget or those seeking a cost-efficient solution without compromising quality may opt for aluminum.

Ultimately, the choice between stainless steel and anodised aluminum Biminis depends on specific needs and preferences. Whether opting for stainless steel or aluminum,
be confident that with an Oceansouth Bimini you are acquiring a meticulously crafted, enduring and innovative marine shade solution designed to adapt to diverse boating conditions.
The global acclaim of our brand and our unwavering commitment to quality establish our products as a trusted choice for individuals seeking high-performance and dependable marine accessories.

Can I fit a clamp on rod rack to the back?

Yes, yet you will need to ensure you have back support poles for the rod rack to clamp onto.

How do I drive on the road with the bimini?

You have two options for folding the bimini:
Option 1: Pack the bimini into the provided storage boot. Unclip the straps and/or support poles (if added), then fold the bimini down flat.
Option 2: If you’ve added back support poles, unclip the front straps, fold them back towards the back support poles (whilst standing up) and zip the fabric into the provided storage boot.

Can I fold my bimini flat both forward and back?

While it is recommended to fold the bimini back, there might be instances where folding it forward is necessary, especially if there’s an accessory blocking the way.

Oceansouth began in 1985 in a small garage in Melbourne, Australia as a part-time project making boat ladders and bimini tops. It quickly grew into a global leader in the design and manufacturing of marine accessories. The company expanded its product line beyond its initial offerings, becoming an industry innovator known for blending functionality with style. This reputation for quality led to national recognition in Australia and a move to a larger manufacturing facility in 1990.

In 2012, Oceansouth established its divisional headquarters in Miami, marking its entry into the U.S. market with the aim of expanding its global presence and bringing Oceansouth to the world. This expansion into the U.S.A. was a huge success, leading to further growth in North America and setting the stage for Oceansouth’s foray into the European sector in 2014, with its European base established in Germany.

With our products now sold in 94 countries worldwide, Oceansouth is the premier market leader in marine and boating accessories.
