Where can I buy architectural hardware?

[Mariana89]

We had our own small store and now we decided to change the location to a new shopping center. At one time we equipped the store with the highest quality materials, so we decided to carefully dismantle and move everything to the new location. But an unforeseen situation happened and we lost somewhere architectural hardware for glass and metal partitions. Where it can be bought separately I can not think of. Help me with advice, please.
