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.
There are three different grades, the 36, 55 and the 105 and they are all designate the minimum ksi or kilopounds per square inch of the anchor bolt. These can be roll threaded or cut and the 55 grade can be changed for the 36 grade if needed. Each one comes with a specific colour code at the end so that identification in the field is much easier. The 36 bolt is blue while the 55 is yellow and the 105 is red.
These specific bolts are made from steel that has a much higher yield strength compared to the normal steel. They are more commonly known as the A36M55 and range from one quarter inch to four inches. There are also available in black and can be galvanised as well.
This company perform all mechanical, hardness as well as revolving capacity testing in- house, and provide only products that are 100% fully traceable. They also give a very complete and precise certification packages which they store electronically. This makes sending out any extra copies very quick and easy.
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.
Before this process can begin the bolts need to be prepared and cleaned. All of them are first wheelabrated which is the use of certain steel abrasives, so that all hot forging scales will be removed. They will then be dunked into a solution of caustic soda which will remove all organic materials. The next dunking will be in sulphuric acid as this helps with the zinc to infiltrate the top layer. The last phase is that they are flooded in a flux solution so that the zinc will respond to the steel.
In 1988 it was sold again and in 1992 they moved to a much bigger facility where they had 85 thousand square feet. They then bought back the hot dip galvanizing line. Other products that they manufacturer besides these are the u-bolts and tie rod assemblies. You will need to make sure that you have the right equipment for any project you are taking on, so why not use tools and bolts provided by true experts.
