Every project has many of its own peculiarities. The F1554 was first introduced in the early nineteen nineties. It covers all anchor bolts that were intended for structural supports to all foundations made with concrete. They can either be headed bolts, bent anchor bolts or straight rods.
This type of bolt is still fairly new and was made by the American society for testing and materials. They cover all steel anchor bolts that are intended to keep all structural supports in place where concrete is used as the foundation. At Portland bolt these bolts are ready to be shipped out at a moment's notice. All galvanised bolts can be changed to the plain finish ones when they are needed promptly.
The Hex bolt is the most commonly used when needed for construction. They have a six sided head and are used for fastening steel and wood as well as for highway structures and docks. The normal products that are produced for any highway include guardrail bolts, barrier pins, traffic pole anchors, light anchor bolts as well as bridge rail anchor bolts and sign structure bolts.
The S1 specification means that the grade 55 is able to be welded through a chemical composition and a carbon formula. If this is not mentioned it means that it might not be able to be welded. S2 is the manufacturer's identification which is everlastingly stamped at the end of the bolt and protrudes from the concrete for easy reference.
The S3 is the same as the aforementioned the only difference is that the grade identification is on the end and also has colour coding. S4 is the impact requirements which are +40 degrees Fahrenheit for grades 55 and 105. The minimum v-notch energy needed is about 15 ft- lbs and none of them are allowed to fall below the 12 ft lbs. S5 impact requirements are at -29 degrees Fahrenheit for the 105 grade. The minimum v- notch is also 15 ft-lbs for all of the specimens.
Portland Bolt is the leading anchor bolt and construction fastener manufacturers in North America and was founded in 1912 by J Llewellyn. By 1916 there were fifteen employees and they were producing an annual sales of over $100 000. When they first started out their main products were bolts, washers, dies, rivets as well as pole pins and different tools for machine shops.
They started off in a 6 thousand square foot stable and in the mid 1920s moved to a much larger facility where they were able to add a hot-dip galvanizing line. In 1974 they sold the business to a Morris Galen and Melvin Peters who were going to fulfil the obligations and then liquidate all the assets. During this time they found out that the business had a lot of potential and decided to sell off the galvanizing line.
The bolts are made of carbon, carbon boron and alloy and are made in three separate strength grades and two thread classes. They are all tested for their tensile strength, yield strength as well as stress areas. They all must stick to specific chemical compositions and are examined by heat and product analysis.
