At Zh Metal Materia’l the quality of our products is the cornerstone of our reputation. We believe that to supply world-class customers, we to must be world-class in everything we do and in every detail of our business.
We always supply high-quality tubing, and do so in a safe, efficient and timely way. We are renowned for our ability to supply tubes of all sizes, which means that we can closely work to your designs.
We only use premium-grade metals to ensure that the quality of our tubes is optimal, and we undergo rigorous testing and checks. Uncompromising quality control and strict traceability is key to the entire Zh Metal Materia’l operations. We are proud of our commitment to quality and efficiency.
We offer the C.N.’s largest range of Super Mirror Marine Polished tube & sheet. This is mirror polished material refinished to provide an unsurpassable finish and depth of colour giving excellent image clarity and surface texture.
At Zh Metal Materia’l we understand how important it is to create visually appealing but durable metal architecture that can withstand an uncompromising marine environment.
From stunning staircases on super-yachts to grab rails on speedboats, our shaped stainless steel tubes offer the marine industry aesthetic, structural and ergonomic advantages over standard round tubing.
Popular marine applications include:
We offer tubing in six different shapes; each design has different properties, with profiles such as oval tubing offering significant advantages over standard round tubing.
For example, D-shaped tube has a smooth top and flat section on the underside that allows water to flow off it, preventing water ingress, which means that it is easier to maintain. Ideal as handrail, its distinctive ridged design creates a flat and secure base, which fixes easily to bulwarks and balustrades.
Twisted oval tube boasts attractive contours that catch the light beautifully, and make for stunning spindles on staircases.
Shaped railings are safer than round tube railings because they are easier to grip. Our grab rails are typically shaped from oval tubing and square radius tubing — hands fit comfortably and securely around these shapes (and unlike round tube, hands are not prone to the same degree of slippage).
Similarly, oval tube boarding ladders are more comfortable to climb and offer better grip than round tube ladders.
Harsh environmental conditions like salt water and constant sun mean that the selection of alloy is critical for marine projects. We make most of our exterior tubing from premium-grade stainless steel 316L (1.4404), which contains a higher nickel and molybdenum content for greater corrosive resistance. The higher corrosion resistance and higher yield strengths of these alloys allow them to withstand far more punishment than the average carbon alloy.
Stainless steel has good weldability and formability, and is scaling resistant. Easy to clean and with strong visual appeal, it is the ideal material for handrails, grab rails, deck fittings, balustrades and furniture.
Refit or refurbishment, brand-new boat design or prototype, the uniquely shaped tubing is a simple way of offering you or your clients greater choice when it comes to the design of the yacht. Our engineers will work hard to fabricate tubing of any size to meet your needs – even if this requires us to make new tooling.
We can also form tubing from bronze or brass, or apply PVD (Physical Vapour Deposition) titanium ion plating to create a brass-effect – or other colours – to stainless steel. If you like traditional teak wood but want to enjoy the properties of aluminium or stainless steel, we can powder coat the tubing with a teak wood-effect.
Clean, rounded lines and flat sides provide strength for architectural purposes. This tube is easy to fix to other elements.
This popular tubing is practical, elegant and strong. Its clean shape and its versatility make it viable for a vast number of applications.
The flat side fixes securely – and easily – to other elements. It is simple to maintain, which is why it is so often used in marine and medical industries.
Tests have shown that this profile is up to 54% stronger than standard round tubing, making it our strongest shaped tube.

An ergonomic, tactile shape that is perfect for handrails and balustrades. This low-maintenance design is commonly used for architectural and marine purposes.
This elliptical oval tubing combines a pleasing aesthetic with an ergonomic and tactile shape.
It can be easily connected with our joiners, enabling fabricators to produce high-quality handrails and balustrades in conjunction with structural glass and brickwork. Weld the tubing to the joiners for an uncompromising seamless form, or simply dry-join them together.

Blended radius corners and a slight convex side provide great strength, making it an attractive substitute for standard box section tubing.
Due to its appealing softened corners and the range of available sizes, it is ideal for balustrade and handrail panels.
Aesthetically striking alternative to standard round or square tube profiles. Offers impressive strength integrity while being lighter and more cost-effective than conventional solid twisted bars.
Not only beautiful, the twisted shape has improved rigidity and deflection capabilities in comparison to round tubes of the same wall thickness and material grade. An exciting form to work with.
Choose between continuous twist or incremental twist.

With a smooth top, flat section and incredible lateral strength, this clever design prevents water ingress underneath, plus it is very easy to install. Ideal for handrail on marine craft and in public buildings.
The D-shaped tube has been developed with ease of installation in mind; its distinctive ridged design creates a flat and secure base to apply to bulwarks, brickwork and balustrades, including glass. (Square-cut balusters can be welded directly to its recess, or a glazing channel can be welded or attached by threading inserts to the underside).
When formed from marine-grade 316L stainless steel, it provides a great alternative to traditional teak bulwark capping or handrail on larger boats and cruise liners, since it requires very little upkeep to remain looking new.

Innovative spiral forming applied to a classic oval tube design. This beautiful twisted tubing creates a mesmeric effect that is ideal for decorative metal architecture on buildings and boats.
Incorporating the classic oval tube design with the spiral forming process adapted from our twisted square tubing, this shape catches the light beautifully.
The tubing is also extremely tactile – the contours of the twists are sophisticated and sculptural.
It can also be joined using the same joining system as oval tubing, allowing fabricators to create high quality handrails and balustrades with ease.
Twisted oval tube is available in the same sizes as oval tube.
Our twisted metal spindles bring enduring elegance to any staircase or balcony. The smooth lines and exceptional finish makes every individual spindle look and feel as if it has been sculpted.
Crafted from both oval and radius square tubing, the spindles come with a choice of four different twists – from a subtle, sophisticated twist to continuous, tight twists for striking visual effect.
You can also create a staircase combining spindles of differing shapes and types of twist — or intersperse them with wooden spindles.
We typically supply spindles from stainless steel 304L (1.4301) for internal balustrades, with a mirror polish or satin finish. They can be fabricated from other metals such as brass, bronze or cupronickel.
Our D-shaped tubing features a curved topside which is ergonomically designed to be gripped as a handrail. It has a flat face on its underside that makes it easy to weld to. Flat-sided oval tubing can also be used.

Each spindle is cut to 1.1m; this extra length of tubing allows for the tube to be cut to fit any sized staircase. (The legal minimum handrail height in private residences is 900mm for staircases and landings).
Our joiners connect oval and twisted oval tubing with a smooth, seamless finish.
They allow you to produce tight joins on handrail and balustrades with greater ease, eliminating the need to cut and weld the tubing. The joiners can work in conjunction with structural glass and brickwork.
When used as a handrail, oval tubing can be dry joined, or joined by welding the joiners into the tube without any visual defects (after polishing).
Used for vertical bends, such as those you might see on a staircase.
Suitable for joining horizontal tubes, such as those used on balconies and handrails.
Used when the application requires a significant length of tubing.
Gently curved components used for furniture and handrailings.
