Custom Gondola Shelving Process: From RFQ and Sample Approval to Mass Production

Quick Answer

Once an RFQ is submitted, the custom gondola shelving process runs through 11 stages: requirement and application review, single/double-sided and end-cap configuration, dimension/UDL/component confirmation, backpanel/color/accessory selection, technical drawings and BOM, sample production, sample revision and written approval, mass production, load testing and QC, packing and container loading, and batch consistency management for repeat orders.

A typical custom project — from written approval of the sample to a multi-container shipment — takes 6–10 weeks, and reputable manufacturers will always produce a physical sample and get written sign-off before mass production starts. Below, we walk through each stage using two real projects — a 3×40HQ container order for a Kenyan supermarket chain and a multi-batch repeat order for an Indonesian retail customer — to show exactly how the process plays out in practice.

Custom Manufacturing Process at a Glance

What Makes Gondola Shelving “Custom”?

Custom gondola shelving is not limited to adding a logo or changing the paint color. A project becomes custom when one or more requirements differ from the manufacturer’s established configuration or require project-specific confirmation.

Common customization fields include:

• section width and overall height;
• base and upper-shelf depths;
• number and angle of shelf levels;
• single-sided, double-sided and endcap combinations;
• starter and add-on bay structure;
• required UDL at a specified shelf size;
• upright, shelf, bracket and panel specifications;
• solid, perforated or wire-mesh back panels;
• RAL colors and surface appearance;
• hooks, baskets, dividers, price rails, fences and signage;
• custom mesh end panels or decorative end panels;
• OEM branding and private-label packaging;
• carton marks, language and store-by-store labels;
• spare-parts quantities; and
• packing method and container-loading requirements.

Every custom field affects another part of the order. For example, a deeper shelf can affect material use, bracket design, load performance, package size and container utilization. Customization should therefore be managed as one approved system rather than a collection of isolated choices.

Confirm Single-Sided, Double-Sided, and End-Cap Configuration

Gondola shelving configuration depends on where each unit will sit in the store layout:

We confirm this configuration against the buyer’s floor plan (if provided) before moving to dimensional specs, since it changes the upright and base structure, not just the shelf count.

Confirm Dimensions, UDL, and Component Specifications

This is where the project moves from a general concept to an engineered specification:

• Bay dimensions: length, width (shelf depth), and height, confirmed per configuration type
• UDL (Uniformly Distributed Load) per shelf — the manufacturer should provide a tested load rating, not an estimate, especially for heavier categories like canned goods or beverages
• Number of shelf levels and adjustability (hole pitch on the upright for shelf height adjustment)
• Base type: standard base, kickplate base, or reinforced base for heavier loads
• Steel gauge and structural components: uprights, shelf brackets, back stiffeners

At this stage we typically issue a structural confirmation sheet so the buyer can sign off on load capacity per shelf before any tooling or material cutting begins.

Backpanel, Color, and Accessory Confirmation

Custom projects usually differ from stock catalog shelving primarily in finish and accessories:

• Backpanel type: pegboard, slatwall, solid steel panel, or open-back — often driven by whether the retailer wants to hang accessories or display signage
• Color matching: RAL or Pantone code matching for brand consistency across a chain
• Accessories: price tag rails, dividers, shelf talker strips, header signage brackets, end panel graphics frames

We lock this in before drawings are issued, since color and backpanel type affect tooling for the powder-coating and stamping process.

Technical Drawings and BOM (Bill of Materials)

Before any sample is cut, the buyer receives:

• Dimensioned CAD drawings for every SKU in the order (uprights, shelves, base, end panels, accessories)
• A full BOM listing every component, material, gauge, and finish
• Written confirmation request — production does not start on a component until the buyer has approved its drawing

This step is what separates a real custom manufacturing process from a generic “we’ll match your reference photo” approach — every component is documented and approved in writing before cutting begins, which is what prevents disputes at the sample or mass-production stage.

Sample Production

Once drawings are approved, we produce a physical sample matching the confirmed BOM. For a standard configuration, this typically takes 7–15 working days.

Case in point — Kenya supermarket chain: for a multi-store rollout project, we produced 15 sample units covering the full range of configurations the client needed (single-sided, double-sided, and end-cap units, in the client’s specified backpanel and color), so the client’s team could physically evaluate the full range before committing to mass production — not just a single representative piece.

Sample Revision and Written Approval

Almost no custom project is approved on the first sample without at least one round of adjustment — this is a normal and expected part of the process, not a sign of a problem.

• The buyer inspects the sample (in person, or via detailed photos/video if remote)
• Feedback is documented against specific components (e.g., “increase shelf gauge,” “adjust backpanel hole spacing,” “match color swatch more closely”)
• A revised sample or component is produced and re-submitted
• Mass production does not begin until the buyer provides written approval of the final sample — this written sign-off is the reference point used during quality inspection later

In the Kenya project, this revision cycle led to adjustments on shelf bracket fit and backpanel finish before the client gave written approval — at which point the order moved to mass production for 3 × 40HQ containers.

Mass Production

With written sample approval in hand, the order enters mass production, referencing the approved sample and BOM as the production standard.

• Standard lead time: 20–35 days for a multi-container custom order, depending on total volume and component complexity
• Production is benchmarked against the approved sample at each stage — the same drawings and BOM used for sampling are used as the QC reference during mass production, not a separate internal spec

Load Testing, Trial Assembly, and QC

Before packing, every custom order goes through:

• Load testing: a sample shelf from the production batch is tested against the confirmed UDL rating
• Trial assembly: a full bay is assembled from production-line components to confirm fit, alignment, and finish consistency — not just individual part dimensions
• Visual and dimensional QC: checked against the approved sample and technical drawings, with results documented for the buyer

This trial assembly step matters specifically for custom projects, because individual components can each pass dimensional checks while still not fitting together correctly if tolerances weren’t controlled consistently across the batch.

Packing, Labeling, and Container Loading

• Units are flat-packed (knocked down) with SKU-specific labeling so store-level assembly teams can match components to the correct bay configuration without confusion — especially important on multi-configuration orders like the Kenya project, where single-sided, double-sided, and end-cap units all shipped together
• Packing includes corner protection and internal bracing appropriate to the component (uprights vs. shelves vs. accessories)
• A loading plan is shared with the buyer before container booking so they know exactly how many containers the order will require

Batch Consistency and Repeat Order Management

For buyers rolling out shelving across multiple stores or ordering in batches over time, consistency between batches matters as much as the quality of any single shipment.

• We retain the approved drawings, BOM, and color/finish reference from the original order as the standing specification for all future repeat orders
• Any specification changes for later batches are documented as revisions to the original file, not treated as a new project from scratch
• This means a retailer expanding store-by-store over months or years receives shelving that matches their first order, without needing to re-approve samples every time

Case in point — Indonesia retail customer: for a customer rolling out shelving across multiple stores over an extended period, we managed the order as a series of batches against a single standing specification rather than as repeated one-off projects — allowing each new batch to match the finish, dimensions, and configuration of the original approved order without a fresh sampling cycle each time.
