For open sections, although the grades are standardised across Europe the sizes are not. In the UK sections are generally produced according to BS 4-1:1993, which converts imperial sizes to metric (26″ becomes 914mm), whereas on the continent the dimensions are truly metric. Hollow sections (RHS, SHS, and CHS) are available in metric sizes which are common both in the UK and across the continent. Hot finished hollow sections are supplied in accordance with EN10210 and in EN10219 for cold formed hollow sections. Although the sections dimension may be identical for both hot finished and cold formed, the capacities are not direct equivalents so care is required to ensure the correct grade is requested. Parallel Flange Channels (PFC) - Otherwise known as C channel beams, PFCs can massively add to a building’s stability and are usually used in structural steel fabrication projects. Masteel is a leading supplier of structural steel sections to many locations throughout the world, supplying a wide range of steel products. The range of shapes (sections as we call them in the UK or profiles as they are more commonly known across Europe) is very wide including universal beams and universal columns.

Universal Columns - Also known as H beams, the differences in their design compared to steel beams make them perfect for use as vertical supports. Tyres Marked like above have four components. The first number is the width of the tyre. The second is the height of the sidewall and the third is the rim diameter. The "-" again means the tyre is a crossply. all figures are in inches. Steel Box Sections - Commonly referred to as hollow steel sections, these products are similar to the steel bars we supply but with open ends to the section that make them look like a tube. Steel box sections come in three primary shapes: square, rectangular, and circular.Universal Beams - Otherwise referred to as I beams or RSJ beams, these are often used for load-bearing projects, such as a structural framework for buildings. The inner tube size you require will depend on the size of tyre being used. The size of the tyre is often written on the sidewall, and a inner tube to fit this size range is required. Because inner tubes are very flexible they can fit a range of tyre sizes, expecially larger inner tubes. A inner tube will fit a range of tyres sizes, which is often printed on the tube but not always. Sometimes only the base tube size is printed on the tube (3.50-6) but it is still ment to fit a range of tyres sizes. There are a few ways for giving the size of tyres. Measurements given in inches and sometimes in millimetres or both. We have shown some examples below to help you recognise the size markings on your own tyre. The first number denotes the width of the tyre and the height of the sidewall in inches. The "-" means that the tyre is of a crossply construction. The last number is the rim diameter in inches. If you’re ready to benefit from quality fabricated steel, here are the products that are available to buy through our online store.

RSJ steel beams are likely the most popular kind of steel beams used in the construction sector today. Both I-beams and H-beams are highly durable RSJs or rolled steel joists which can be cut to any size. This makes them great for supporting the ceilings and floors in a home extension, for instance. Brushed and oiled – Steel brushes are used in the direction of the grain which opens up the surface of the wood and removes splinters. The wood is then oiled. We do NOT decide if an item is or isn’t exempt & we don’t make any more or less money if we charge you VAT or we don’t charge you VAT. Whenever you want to build an open plan space via modifying or completely removing a load-bearing wall, you must install an RSJ beam to withstand the strain. Hot rolled RHSs are made one piece, whereas cold formed RHSs are made of a flat sheet rolled at right angles and welded.Since a universal beam has an increased depth compared to other kinds of steel beams, it has a higher loading capability too, making it very versatile for all kinds of civil engineering and home improvement or residential build projects. Mild Steel Bars - Strong and dependable, these are solid pieces of steel that come in a wide variety of shapes and dimensions depending on the needs of your project, including flat, round and square bars. So, if universal columns are used in commercial construction where structural support is required, for example, in supporting floor joists, universal beams (also called I-beam) are typically found in the majority of applications in girders, because they possess a much higher moment of inertia in contrast with universal columns. This makes them more resistant to bending moments owing to the different construction loads, such as self-weight. Inner tube sizes and valve types. This guide gives a basic description and purpose of the most common types of inner and valve shapes. If you fail to return any VAT exemption forms to us we WILL charge your card for the outstanding VAT.
