Buying grey exterior terracotta bricks is a coordinated procurement exercise, not a colour-and-price decision. Product code, fired range, module, corner pieces, quantities, batches, wall-system evidence, packing, delivery and spares must align before an order is released.
Turn an enquiry into an exact product brief
Request a current product code and drawing showing length, height, thickness, tolerances, edges, rear profile, unit mass and intended installation route. Verify whether 60 × 240 × 11 mm remains current and whether the item is a bonded veneer, mechanically supported unit or another wall product.
State facade area, location, exposure, substrate, system concept, module, joint intent, colour range, specials, programme and required evidence. A quotation based only on square metres can omit corners, cuts, tests, packing or technical responsibilities that materially change scope.
Ask the supplier to distinguish stock, scheduled production and made-to-order availability, with a date for each statement. “For sale” is not a reservation of quantity or batch. Record sample, approval, production and shipping milestones separately so an early catalogue selection does not become an assumed delivery promise.
Approve a purchasable grey range
Review several current samples under representative daylight and artificial light. Define light, middle and dark boundaries, warm or cool undertones, texture, edge character and permitted variation. Compare adjacent glass, metal, stone, sealant and paint at the same time.
Label approved samples with code, finish, date and source batch. Decide whether the facade needs a quiet blend or deliberate variation and document batch-mixing rules. Digital photographs help communication, but retained physical samples should govern procurement and visual acceptance.
Build quantities from the facade module
Field units
Calculate from surveyed or coordinated elevation areas, unit-plus-joint module, openings, bond and zone-specific layouts.
Cuts and waste
Use the actual corner, opening and transition strategy rather than applying one unexplained percentage to every elevation.
Special pieces
Schedule corners, returns, soffits, sills or other shapes by code, orientation and location, not by a generic allowance.
Spares
Agree handover quantity, matching expectations, labels and storage so future repairs can use traceable units.
Reconcile architectural take-off with supplier packing quantities, pallet limits and order tolerance. Keep alternates visible: a field cut, factory corner and different return detail may have different appearance, lead time, breakage and installation implications.
Issue the quantity schedule by elevation and piece type, with drawing revision and measurement basis. Recalculate after openings, corners or bonds change. This provides a controlled route from design to purchase order and helps locate overage or shortage before production is complete.
Resolve corners and transitions before release
Obtain current drawings and samples for any corner or special piece. Confirm face dimensions, return depth, radius, colour, texture, rear geometry and compatibility with the selected system. If factory corners are unavailable, draw the approved cut or paired-unit solution at full size.
Coordinate external and internal corners, openings, bases, parapets, soffits and adjacent materials. Check whether module changes create extra cuts or special orientations. Record which pieces are left- or right-handed and how they will be labelled and packed.
Control batches, production and packing
Agree the production range, inspection plan, retained references, sampling frequency and response to out-of-range colour, dimensions or damage. Ask how order, batch, kiln run, inspection, packing list and pallet labels remain connected. Define whether production changes require resubmittal.
Where project scale or colour sensitivity warrants it, review early production against the approved range before the full run proceeds. Retain labelled units from the accepted batch. Record who can release production and how later drift or replacement production will be assessed.
Review carton quantity, pallet dimensions and mass, protection, stacking, container or truck plan, lifting and delivery sequence. Packing should protect faces and edges and let site teams identify batches without unpacking every carton. Confirm current information instead of copying the archive phrase.
Verify evidence and commercial scope
Create a matrix for product dimensions, absorption, strength, freeze–thaw, chemical exposure, reaction to fire and other relevant criteria, plus wall support or adhesion, water management, movement and wind actions. Check code, thickness, finish, method, laboratory, date and scope.
Archive terms such as “firebrick” or “heat insulation” do not establish complete-wall outcomes, and a management-system certificate does not prove product performance. Separate unit price, specials, samples, mock-ups, testing, inspection, freight, duties, installation materials and site work so offers can be compared.
Use a submittal and change register with revision, status, reviewer, qualifications and open actions. If a report, product, finish or plant changes after quotation, require a documented review before purchase or production continues. Commercial urgency should not silently redefine the approved technical package.
Receive, install and retain traceability
At delivery, reconcile purchase order, packing list, pallet labels and batch records. Inspect damage and sample dimensions and colour under the approved plan. Store cartons dry and protected, and distribute batches across planned areas rather than allowing delivery sequence to set the facade blend.
Review the current terracotta brick range and relevant project references for initial context. At handover, retain as-built batch locations, approved cleaning and maintenance guidance, repair principles and labelled spares.
