One supplier for doors and railings: what it saves on site

You are building a block, and your procurement list has fire doors from one supplier, entrance doors from another, technical doors from a third, and railings from a metalwork shop that has never seen the door schedule. Every one of those relationships is a schedule to align, a quality standard to police and a phone call to make when something slips. Sourcing doors and railings from a single manufacturer removes most of that overhead — and on a whole building the overhead, not the unit price, is where projects lose time.

The real cost of many suppliers

The price on each quotation is the visible cost. The invisible cost is coordination, and it lands on your project manager:

• Schedules that do not line up. Four suppliers means four lead times, four delivery windows and four chances for one of them to arrive late and stall an inspection.
• Quality that drifts between vendors. A steel finish from one shop does not match the next. Tolerances vary. The building ends up looking assembled from parts, because it was.
• Handover in fragments. Fire-door certificates come from one vendor, warranties from another, and the facilities team inherits a folder nobody owns.
• Blame with no address. When a railing does not fit the stair the doors were measured for, two suppliers point at each other and your PM arbitrates.

None of this appears as a number on a bid. All of it consumes the one resource a developer cannot buy back: the schedule.

What one manufacturer changes

Unigon DOORS makes the full envelope of a building's steel openings and railings, so the coordination collapses into a single relationship.

The point is not that a single supplier is automatically cheaper per unit. It is that the whole package arrives as one package — planned together, finished to one standard, handed over in one set.

The product range behind it

A single relationship only helps if that supplier genuinely makes everything. Unigon's range covers the building's steel openings and its railings:

• Fire doors — EI 45, EI 60, EI 90 and EI 120, certified, for corridors, stairwells, technical rooms and compartment lines.
• Entrance doors — EI 30 and EI 60, built from a reinforced steel skin, an aluminium core and a rock-wool fill, in RAL custom colours and made to measure.
• Technical and shaft doors — for plant rooms, risers, meter cupboards and utility spaces, in steel with a powder-coat finish.
• Modular railings — balcony, stair and fire-escape railings, made to the project's dimensions.

Because all of it is produced to the same project dimensions, the railing that meets a stair was made to the measurements the doors on that stair were made to.

How the modular railings work

Railings are where "one supplier" pays off most visibly, because the way Unigon builds them is designed for the site, not just the workshop.

• Robotic laser-welded joints. The modules are welded by robot, so the joints are precise and clean — no prominent weld nodes to grind back and hide.
• Galvanized, then dip-coated in black. Each module is galvanized for corrosion resistance, then the black anti-corrosion paint is applied by dip-coating, so coverage is even and gap-free — into the corners a spray gun misses. This matters for balconies and fire escapes exposed to weather, especially near the sea.
• Installed like LEGO. The railings arrive as finished factory modules that bolt together on site. On-site work becomes assembly rather than cutting, welding and painting in place — faster, cleaner and far easier to schedule around the rest of the build.

Balcony runs, staircases and fire-escape stairs are all made to the project's dimensions, so what ships is what fits.

A short checklist for single-source supply

• One schedule covers doors **and** railings, with delivery windows aligned.
• Fire-rated openings carry their required class, confirmed per the building's fire-safety design.
• Entrance, technical and shaft doors are specified in RAL colours and sizes per opening.
• Railing runs — balcony, stair, fire-escape — are listed with dimensions.
• The certificate and handover pack is agreed as one delivery at the end.
• One named point of contact owns the whole package.

One call, one package

If you are planning supply for a block, send us the door schedule and the railing runs together. We quote doors and railings as one package, built to your project's dimensions, aligned to your programme and delivered across Tbilisi, Batumi, Kobuleti and Rustavi — one supplier, one point of contact, one handover.
