Logo Design - New Company

This is what SafeFe was looking for in their logo design

I need a logo for a new company. The company name is SafeFe and deals with high tech safety products mainly for use in the metals (steel) industry - thus Safe and Fe the element for Iron. The logo should seperate these two words in someway but at the same time show that it is one word so that people can easily remember it and google it later.

The website will be www.safefe.com which will also need to be developed.

I would like the logo to have elegent and professional styling, and must be easy to use in different types of branding such as web sites and on products - therefore it shouldnt be over complicated.

I am open to all suggestions, good luck.

**Update :
Please no more designs with Safe and/or Fe in boxes please think outside of the box.
Also - it is not safe as in lock but safety - lock / key concepts are not working for me

Thanks
