Tube is commonly used for a wide range of purposes including food & beverage process lines & structures, irrigation, pumping, petrochemical, geothermal, marine, agriculture and machinery, automotive, and architecturally.
Tube is cold rolled which means that it has been rolled from a stainless steel coil while cold. This results in a smooth hard finish. It is normally finished with a 180 or 320 grit polish, although it can also be polished to even smoother finishes. It comes in different shapes such as square, rectangular and cylindrical.
Tube is measured based on the OD or outside diameter and wall thickness.
Round tube can be polished internally to make it hygienic, which is commonly known as Dairy Tube in New Zealand. Our Dairy Tube is manufactured to the AS1528.1 Standard. The naming convention for Dairy tube in NZ uses imperial inch sizing, so its commonly known as 1”, 2” tube etc.
General Purpose Tube is the same as Dairy Tube but the weld seam hasn’t been polished. It’s also commonly known as hand rail tube. This makes it a more economic alternative for non-hygienic applications that use Dairy Tube sizes such as glycol or handrails.
Square and Rectangle tubes are commonly used for building structures and frames. They are polished to a 180 grit finish making them an ideal material for use in clean environments. We stock a range of sizes and thicknesses from ½” Square tube right up to 150x100x5 Rectangle tube in 304 & 316 Grade Stainless.
Press-fit Tube is measured metrically and fits our press-fit system. This is available in both 304 & 316 from 15mm to 108mm. We can get bigger sizes up to 168mm as needed.

WaterMark vs General Purpose RapidPress Tube
Watermark Approval is a mandatory certification program for specific plumbing and drainage products to ensure that they are appropriate and authorised for use.
The WaterMark program operates on a five-year certification cycle, with yearly product surveillance.
The RapidPress Watermark approved Tube is produced in Europe alongside our press-fit fittings using 316L grade material. This is essential for meeting Watermark Approval requirements and potable water applications. We stock watermark tube in sizes ranging from 15-108mm.
Our standard RapidPress Tube is manufactured by the same mill in Taiwan that produces our Dairy tube. This tube is not accompanied by Watermark Approval and is typically utilised for various services, including compressed air, glycol, wash down, and wastewater, but not for potable water applications.
It is important to recognise that WaterMark approval is important when it comes to potable water usage. However, for other non-potable water applications, Watermark is not necessary and does not provide any inherent advantages. Our standard RapidPress tube is perfectly suited for such applications.

These are used when connecting BSP with imperial tube as normal BSP weld nipples and sockets don’t work nicely with imperial tube.
We stock two different types of BSP to tube adapters. A weld nipple adapter, also known as a reducing weld nipple, and a weld socket adapter, that was developed by The Metal Company. Both of these fittings are machine finished from high quality 316 stainless steel.
A weld nipple adapter has a tapered male BSP thread on one side, and on the other side it butt welds directly to imperial tube or tube fittings. Something unique about our weld nipple adapters is the internal diameter of the tube continues right until the chamfer, which reduces the impact on flow.
A weld socket adapter has a female BSP Threaded socket on one side, and on the other side it butt welds to the outside diameter of tube or tube fittings.
A unique feature of our adapters that we developed is that they have a flat spot to allow you to tighten the fitting more easily. No more scratched up fittings!
We stock both adapters in sizing from ½ an inch to 4 inches.
These adapters also form the base of a lot of other BSP Adapters we stock, such as our RJT-BSP adapters, Tri Clover to BSP adapters and more.

Differences Between Dairy Tube & General Purpose Tube
Both tubes look exactly the same on the outside, it’s what is on the inside that counts.
When tube is formed there is a weld bead created where the two edges of the rolled stainless meet. The tube is then polished externally to a 320 grit finish, and if it is going on to be Dairy Tube it is also polished internally to remove the weld bead and create a hygienic internal surface. Dairy Tube is therefore suitable for food and beverage lines.
Since General Purpose Tube still has the weld bead on the inside it is suitable for non-hygienic uses such as glycol, wastewater and handrails. General Purpose Tube is typically cheaper than Dairy Tube due to having one less step in the production process. General Purpose Tube is also known as Handrail Tube.

In the world of engineering and construction, the acronyms RHS, SHS and CHS are often used. This is most common in the United Kingdom and associated countries, including Australia and New Zealand.
The term RHS stands for Rectangular Hollow Section. RHS is the most prevalent term and is generally accepted for describing square hollow section as well, which is technically incorrect.
These terms are widely used to describe mild steel; however, they can also be translated for stainless steel and aluminium engineering and construction by engineers who are familiar with the terminology.
Other common terms include Box Section, Extrusion and Profile. Box Section can refer to either rectangle tube or square tube. Extrusion and Profile are terms that can be used in place of ‘Section’; however, this is more applicable to material which has been particularly configured or shaped rather than rectangle, square or circular hollow tube.
The Metal Company stock a full range of SHS, RHS & CHS in 304 & 316 Stainless Steel.

Sizing is based on the outside diameter and wall thickness (gauge) of the tubing. The standard stainless steel tube is measured by the outside diameter up to 6” size.
Stainless Inside Diameter (ID) Tube
Sizing is based on the inside (or internal) diameter and wall thickness (gauge) of the tubing. The standard stainless steel spiral weld tube is measured by the inside diameter from 6” size onwards.

Stainless Inside Diameter (ID) Tube
Sizing is based on the inside (or internal) diameter and wall thickness (gauge) of the tubing. The standard stainless steel spiral weld tube is measured by the inside diameter from 6” size onwards.
Spiral welded tube is created using a process where a continuous full penetration MIG (metal inert gas) weld overlay is used to create tube in a spiral pattern. Typical industry applications include HVAC / refrigeration, geothermal, liquid transfer, waste water, irrigation and pumping.
Our spiral welded tube and fittings are manufactured to internal dimensions. This means sizing is based on the internal diameter and wall thickness (gauge) of the tubing. All our spiral welded stainless steel tube is manufactured from high quality coil conforming to ASTM: A240.
Aside from the standard range, The Metal Company can source or manufacture various spiral welded tube and fittings within New Zealand or internationally. Options available on indent include spiral welded tube and fittings in stainless steel grade 316, spiral welded tube up to 8 metres in length and spiral welded tube and fittings in sizes up to 24″.

Pipe is commonly used for a wide range of purposes including, transporting fluids, gases, drainage & services, irrigation, pumping, petrochemical, geothermal, marine, agriculture and machinery.
The term NB (Nominal Bore) is often used interchangeably with NPS (Nominal Pipe Size). ‘Nominal’ is a non-dimensional number that identifies the hole diameter.
The wall thickness of pipe is determined by the schedule. In the engineering industry, this can also be written to as ‘SCH10’ or ‘S10’ for Schedule 10S and as ‘SCH40’ or ‘S40’ for Schedule 40S. To ensure correct supply, always specify at least 2 dimensions you require: Outside diameter, inside diameter, or wall thickness.
