as recently the aluminium price goes up to the highest in the human history, we have invented stainless steel 201grade profile to replace the aluminium profile in the curtain wall system.
previously only when aluminium profile strength is not fit enough to use s.s. profile, but now due to the high price of aluminium cost, s.s. 201 price is better than aluminium now.
if want cheap material we can use carbon steel with spray coating.
below is the drawing for 101 sample of curtain wall system use by steel profile.
all sample profile are available for sales.
