Every edge bevel, drill hole, and tempering cycle should carry its weight in your P&L.
Glass distributors offering in-house fabrication—cutting, edging, polishing, tempering—sit on a margin goldmine. But too often, that gold leaks out due to fuzzy cost models, inconsistent pricing, or legacy quoting habits.
Whether you’re customizing laminated glass for commercial interiors or CNC-drilling ceramic panels for industrial applications, you need to know: Are you actually making money on those value-adds?
Why Fabrication Margin Modeling Matters
Unlike commodity resale, fabrication introduces variable costs:
Labor hours: Skilled work like polishing or mitre edging commands higher wages.
Machine time: Waterjet cutters, tempering ovens, or drill stations burn electricity and require maintenance.
Scrap rates: A miscut laminated pane isn’t salvageable—it’s sunk cost.
Setup time: Changing tooling for a one-off order? That’s lost throughput.
Without a precise model for these inputs, many distributors underprice small-run or complex jobs, assuming they’ll “make it up on volume.” They rarely do.
Building a Fabrication-First Margin Model
Here’s how to create one:
Map Your Services
Break down all custom services into units: edge finish types, hole drilling, tempering, CNC routing, etc. Know what each one costs in machine time, labor, and scrap potential.
Create a Tiered Pricing Matrix
For example, edge polishing may cost $1.50 per linear foot at standard speed, but $2.25 at priority turnaround. Hole drilling may be flat-rate or volume-based.
Factor Setup & Changeover
If a fabrication order requires setup exceeding 20 minutes, model that time as a separate line item or minimum charge.
Model Loss Rates
Track which services have the highest redo rates. Complex beveling or batch tempering often result in scrap or rejects—build a margin buffer.
Segment by Order Size
One-off orders (<5 units) carry far more cost per unit than batches of 100+. Your pricing should reflect that.
Blend Fabrication with Core SKU Cost
Don’t price fabrication in a vacuum. Start with your glass sheet’s landed cost and layer in service premiums based on complexity and volume.
From Guesswork to Strategic Quotes
With a well-modeled margin structure, quoting becomes a strategic act—not a scramble. You can:
Provide faster, more accurate custom quotes
Train junior reps to quote without fear of underpricing
Prioritize high-margin services like digitally printed glass or acid etching
Say “no” to loss-making jobs with confidence
:
In-house glass fabrication isn’t just a service—it’s a business within your business. When you model your margins correctly, you stop guessing and start growing. And in a market that’s demanding more custom, more fast, and more value, that kind of clarity pays dividends.
