Where to buy aluminium floor strip? I've seen it used for uneven or a step-down in flooring. I've seen them on floors of shopping mall where there's a small step-down in areas where theres a roadshow or promotion going on. Anyone know what I'm refering to and where to buy them?? Thanks.

Try to ask at the hardware shop. My sister ordered a piece of s/s U channel that is wider than standard to be used n my car runway for water drainage. But not cheap lah...
