In the case of relieving angles, the typical shim requirements used are almost always require a single slotted.  The stock version of this is 3鈥� wide.

For anyone looking to looking to create a post hole before laying down concrete, the process can be a nightmare.  Some steel fabricators will use PVC pipe or a hard rubber tube to create the hole, but that rarely ever solves the problem.  Often, it can be difficult to keep the pipe or tubing in position while pouring the concrete, and after it can be a headache to remove the tubing once the concrete has set.  However, steel fabricators no longer have to worry about setting down post holes鈥攖he EZ Sleeve is here!

As engineering standards continue to develop and improve, there seems to be an increasing need for weldable rebar anchors and couplers.   To the average fabricator, these wealth of options represent an opportunity for additional profit but requires some understanding of how each system works.

Will the cost of the hot rolled trend go down in 2015? Maybe, but don鈥檛 bet the ranch.

Regarding anchor bolts, ASTM A449 is not a material that should be specified. Regardless, our steel fabricating customer often see drawings calling out for A-449 anchor bolts or fully threaded studs. This is frequently DOT Highway work, where AASHTO specs are more common.

Regarding anchor bolt manufacturing, S-1 refers to a section in the ASTM F1554 Specification. The current version is F1554-07a. Under the Supplementary Requirements, section S-1 reads;

The askew head bolt is always and only used in connection with the wedge insert. This system is most commonly employed to secure relieving angles although it can be found in many other instances where steel members will be bolts to concrete.

Note: PTFE is the generic name for what people often refer to as Teflon庐. Genuine Teflon庐 is a registered trademark of the DuPont Corporation. Most of the slide bearing assemblies that The 亚博系列全平台入口 Supply Company provides are made with Fluorogold庐, which is a PTFE and Fiberglass composite. Fluorogold庐 is a registered trademark of the Saint-Gobain Corporation.

The term S-1 or S-1 Supplement is taken the ASTM Specification, F1554. In Anchor Bolt manufacturing, the F1554 specification is the rulebook. It spells out all the criteria a manufacturer must follow in order to provide a finished product that will perform as the engineer intended. The current version is F1554-07a.

We have seen an increase in demand for in 2014, no doubt in conjunction with the increase in construction projects in general. Occasionally the requests are urgent, with the customer hoping for next day delivery. Often, these are fabricators who intended on manufacturing their own shims and realized time was running out.
