You will need the right equipment for any project you undertake. The ASTM F1554 is an anchor bolt that can take the form of being bent or headed. The headed bolts are non threaded and have a forged hex, square headed or a heavy hex head. The tip is rooted into the concrete foundation where it will lock any steel columns, bridge rail or light poles firmly in place.
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.
The grading of the 36 is that it has low carbon with a ksi yield steel anchor. The 55 has a high strength capacity with low alloy and the 105 is heat treated and of alloy, also with high strength capacity. Supplementary testing will only be done when specifically asked when purchased.
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.
This enables the companies to produce the different parts much faster and to ensure that the clean threads will fit the nuts much securely. The life expectancy with this method can be longer than thirty years and all parts will be coated evenly. As zinc bonds to steel it will provide protection that is permanent.
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.
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.
