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.
The bent bolts have a right angle bend and are also unable to be pulled out. The threaded part is at one end and the L shape at the other. The hook is set into the concrete giving it extra anchorage. The headed bolts are actually turned and used upside down and inserted into concrete. The threads are showing and protrude from the concrete while the head is anchored well. A round plate is then welded to the head where extra strength is added.
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.
For all marine projects these bolts need to be hot dipped in galvanised or stainless steel. This helps to prevent corrosion and ensures that their strength is intact. Stainless steel in also known as inox steel and has some chromium content added. It does not generally stain with water but this can happen in low oxygen, poor air circulation and high salinity areas.
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.
Galvanising is a way of applying a zinc coating to the steel, aluminium or iron as a means of preventing rust from happening. The commonly used method is hot dip where they are immersed in a bath of molten zinc. The temperature will be as high as 460 degrees Celsius and when they are exposed to the air the zinc will respond to the oxygen. It will then form a zinc oxide which will further react with the carbon dioxide where it will form zinc carbonate.
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.
