	* Steel girder blocks can often support each other.  When girders are "glued" together, their joints will become red. 
* Both ends of a girder must be supported. 
* It helps to build a girder high on the page and let it fall until it reaches its supports. Sometimes you need to patch a long girder with new pieces if it separates while it is falling. 
* You can suspend some girder pieces from other girder pieces. 
* If you end up with a few misplaced girder pieces, you can erase them with the white square block.
