What we need from you in this work scope is the metal sliding roller ( see below )
If you can support to fabricate & supply on above sliding roller.
Then this would be a good fruitful start for our local collaborations in a projects.
This time it's more practical to take the metal sliding profile locally, than abroad, more cost effective and easy approval for back & fort correspondence to project consultant. But soon from the other project requirements we would be needing your expertise in metal products customizations for sure! We are not metal manufcaturer, and even we are not metal contractor. We are an Archetictural System Solution Provider to our ME clients. We used to connect only to some metal manufacturer especialized in Archetictural profile/designs and bring in their materials in the projects we are working in the Middle East.

Going back to this Roller Sliding, the drawings I shared for condo and hotel is for one Building requirements.
If you could pleas study the roller sliding drawings and as per the photos of mock up in the site.
Then I'm sure you can draw and develop a better roller sliding system of what they ( client ) want.
If you have further questions or clarifications please let me know.
Thank you & Regards,
