Working With Concrete

In the roof anchor business, it doesn't matter if its retrofit or new construction. Reinforced concrete is the best of the best when it comes to a structure to work with. It's more cost effective, doesn't typically require localized reinforcing or access to the underside of the structure. It also has a host of other benefits as well such as improved insulation and sound barrier qualities.

The best part in new construction is that we don't have to send anybody to the site for installation which saves everybody time and money. We simply send the anchor to the site with our shop drawings and the anchors are cast in place. There are three types of cast in anchors: single stud, four stud, and fully embedded.

Single stud are the most difficult to physically place for casting in as they only have one bolt from which to balance the anchor.

Four stud are much easier to cast in. As you can imagine they have four studs or bolts from which to vertically support the anchor. These extra three studs are required by engineering for taller anchors.

 And finally we come to fully embedded. This is my personal favorite for two reasons: one its very east to stand up for casting, two, it is more cost effective than both the single and four stud anchors.

In the unfortunate event that a pour is missed by the roof anchor manufacturer and the anchor have to be retrofitted, its not as bad as you think. We simply have use an adhesive anchor and glue, or epoxy the roof anchors into place.

There is also an option of using a bolt through style anchor in the chance happening that is pour is missed to retrofit the anchor it but I would not recommend it. The bolt through style anchor requires access to the underside of the structure to complete installation and it also requires leaving a plate exposed.

For its strength and forgiving nature, concrete is definitely the structure of choice for roof anchor manufacturers.
