F1554 Bolts Have Become An Industry Standard

By Ida Dorsey


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 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.

There are even bolts that are dipped in galvanised steel. This means that the steel or iron has gone through a chemical procedure that will help prevent it from rusting. The steel will be coated in a few layers of zinc as rust cannot damage this kind of defensive metal. The general purpose of this is that excess zinc will be left in the threads thus helping to prevent the nut from threading onto the fastener.

Rust or iron oxide helps to speed up corrosion by making more iron oxide. As this happens the outer edges of the exposed steel will flake and fall away leaving a much weaker structure behind. Chromium will form a covering which helps to prevent the spread into the inner structure.

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.

Unfortunately the grade 55 thread rods are not easy to find but they can be made to order. Many people that use these bolts are keen to look up the specifications and these are available on PDF through the Portland Bolt Manufacturing company. They even have a live chat facility available so that all questions regarding fasteners and bolts can be answered immediately.
