Silanes are a hot new item in the replacement of chromate, phosphate, and other metal pretreatments in the metal finishing industry. This includes the use of silanes as a substitute for the zinc phosphating of cold rolled steel. You'll have to investigate further to determine if silanes represent a cost effective option for the company you are working with. At the 1998 US EPA Region 5 Waste Minimization/P2 Conference, in Chicago, Dr. Wim van Ooij (see below) gave a presentation on silanes and identified the following background articles:

I received a call from someone working for a company (wants to stay
anonymous for now) . They manufacture cold rolled steel components
for commercial construction suspension systems. They want to improve
their product's corrosion resistance by swiching to a hot dipped
zinc/galvanizing system. They want to know two things:
Is there a environmentally better substitute for hot dip zinc/galvan steel?
If they use hot dip zinc/galv/steel, is there a market for the scrap they will
