Bike Parking Product Materials
Reliance Foundry’s bike parking stands, bike bollards and lockers are cast or fabricated from high quality materials, providing durability & strength
Reliance Foundry’s bicycle parking racks, bike bollards and cycle storage lockers are manufactured from various high quality materials. All are made to be durable, stylish, and require little maintenance.
Low Carbon Steel
Many of our steel bike racks, bicycle lockers and bike bollards are fabricated and welded using high quality, low-carbon steel. These fabrications provide confidence for stand-alone settings, and provide superior strength to stand the test of time. Steel is an alloy consisting mostly of iron, with carbon content between 0.2% and 2.1% by weight, depending on the grade. Many other alloying elements are used such as manganese, chromium, vanadium, and tungsten. Varying the amount of alloying elements in the steel controls qualities such as the hardness, ductility, and tensile strength.
Steel with increased carbon content can be made harder and stronger than iron, but may also be less ductile.
Cast Ductile Iron
Many of our decorative bike parking castings are available in ductile iron. Cast ductile iron (aka 'spheroidal graphite cast iron') is an alloy that is much stronger than standard cast iron. It is a robust metal that well withstands the elements and physical abuse a bike stand often takes.
Ductile iron differs from grey iron. Grey iron was the original "cast iron" or "wrought iron” and is an iron alloy characterized by a relatively high carbon content. The carbon in grey iron exists as tiny, irregular flakes within the structure of the metal, leading to cast iron's characteristic brittleness. However, in ductile iron, the graphite is in the form of spherical nodules rather than flakes, thus inhibiting the creation of cracks and providing the enhanced ductility that gives the alloy its name.
Reliance offers several bike bollards and bicycle racks in attractive stainless steel. Stainless steel is an alloy with a minimum of 11% chromium content by mass. Stainless steel does not stain, corrode, or rust as easily as ordinary steel (it stains less, but it is not stain-proof). It is also called corrosion-resistant steel. There are different grades and surface finishes of stainless steel to suit the environment to which the bike racks will be subjected in their lifetime. Stainless steel is popular to use in architectural metalwork as it helps minimize oxidation or rusting in the toughest elements.
Some of our bike parking products are available in 316 stainless steel, while others are available in 304 stainless steel;
- 304 Stainless Steel is the most versatile and widely used stainless steel. It is readily formed into a variety of components for applications in the industrial, architectural, and transportation fields. Grade 304 stainless steel provides good corrosion and oxidation resistance; however, this stainless grade will tarnish in service. This alloy is slightly cheaper than grade 316 stainless steel, which possesses improved oxidation resistance. 304 stainless steel exhibits slightly higher strength and improved wear resistance over grade 316 stainless steel.
- 316 Stainless Steel is the second most widely used stainless steel grade. It is readily formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Grade 316 stainless steel possesses better overall corrosion-resistant properties than 304, and is particularly resistant to salt water corrosion. 316 stainless steel is only about 85% as strong as 304, and is more expensive due to its improved oxidation resistance.
