Running Cost 1 : Facility Lease
Lease Magnitude
Your fabrication facility lease is a substantial fixed outlay, hitting $22,000 monthly. This cost directly impacts your break-even point before factoring in payroll or utilities. You must confirm the required square footage aligns perfectly with production needs now.
Inputs Needed
This $22,000/month covers the physical footprint needed for heavy steel fabrication and CNC machinery. To validate this number, you need firm quotes based on your projected square footage requirement and prevailing industrial lease rates in your chosen operational zip code. This is a foundational fixed expense.
Optimization Tactics
Never over-lease space early on; square footage needs scale with production volume. Push landlords for tenant improvement allowances to offset initial build-out costs. If you sign a long-term deal, ensure clear exit clauses or subleasing rights are included. It's defintely better to scale up later.
- Verify minimum required sq ft.
- Negotiate tenant improvement funds.
- Check early termination penalties.
Fixed Cost Pressure
Because the lease is fixed at $22k monthly, every dollar of revenue must cover it before touching variable costs like the 85% Heavy Haulage rate. Low utilization means this large fixed cost crushes your contribution margin quickly.
Running Cost 2 : Core Staff Payroll
Core Staff Cost
Your baseline fixed payroll for essential operational staff hits $50,830 per month. This covers 6 full-time employees (FTEs) including management, engineering, supervision, and quality assurance, but you must budget extra for payroll taxes and benefits later. That's the floor for running the fabrication shop.
Payroll Inputs
This $50,830 covers the base salary for six critical roles needed to manage production and quality control. You need quotes for specific roles-like an Engineer salary versus a Supervisor rate-to build this estimate. This cost is a major fixed expense, sitting right behind facility lease in the initial budget.
- 6 FTEs: GM, Engineers, QA, Supervisors.
- Base salaries only; exclude 25% to 35% for taxes/benefits.
- This is a non-negotiable fixed overhead.
Managing Headcount
Don't hire all six FTEs on day one, especially engineers, if volume doesn't support it. Delay hiring the General Manager until production volume justifies the salary. You can temporarily contract out specialized QA functions to reduce immediate fixed burden.
- Stagger hiring based on production milestones.
- Use fractional or contract Engineers initially.
- Ensure supervisors are cross-trained immediately.
Tax Reality
Remember, the $50,830 is just the gross pay. For accurate cash flow planning, you must add employer-side payroll taxes (like FICA/FUTA) and benefit costs. Honestly, expect the true monthly cost for these six people to easily push past $65,000 once compliance is factored in.
Running Cost 3 : Equipment Maintenance
Lock In Uptime
You must budget $4,500 monthly for the fixed maintenance contract covering essential fabrication gear. This fee guarantees uptime for high-value assets, like the CNC Plasma Cutting System, which directly impacts your ability to deliver custom structural components. Don't treat this as optional; it's preventative capital preservation.
Maintenance Cost Structure
This $4,500 monthly payment secures a service agreement for your heavy machinery. It covers scheduled preventative checks and rapid response for the plasma cutter, which is central to creating hexagonal openings in steel. This fixed cost must be included in your initial $22,000 facility lease and $50,830 payroll when calculating initial burn rate.
- Covers critical asset uptime.
- Fixed cost, not usage-based.
- Essential for quality control.
Managing Service Fees
You can't easily cut this fee without risking downtime, but careful contract negotiation helps. Look closely at response times and parts stocking clauses included in the agreement. A common mistake is signing multi-year deals before production volume stabilizes. We defintely need to benchmark this rate against industry peers next year.
- Benchmark service rates now.
- Negotiate parts stocking levels.
- Avoid long-term lock-ins early.
Risk of Skipping Coverage
If the CNC system fails unexpectedly, the cost of emergency repairs and lost production far exceeds the $4,500 monthly contract fee. Failing to budget for this maintenance directly jeopardizes your ability to meet delivery schedules for general contractors. Downtime is profit erosion, plain and simple.
Running Cost 4 : Insurance Coverage
Fixed Insurance Cost
Insurance coverage costs a fixed $6,800 per month, which is non-negotiable for mitigating fabrication risks. This expense is critical overhead for structural manufacturing operations.
Liability Inputs
This $6,800 covers liability essential for heavy fabrication risks associated with cutting and welding large steel components. Inputs needed are projected annual revenue and asset valuation for accurate quoting. This cost is fixed overhead, similar to the $22,000 facility lease.
- Covers heavy fabrication liabilities.
- Rate based on asset value.
- Fixed monthly burn rate.
Managing Premiums
Since this is essential, optimization centers on risk management, not rate shopping alone. A strong safety record directly impacts your renewal premium; keep compliance tight to defintely avoid costly claims. Shop coverage annually for better terms.
- Maintain excellent safety records.
- Shop coverage annually for better terms.
- Ensure policy matches fabrication scope.
Early Stage Burn
This $6,800 fixed cost eats into early margins if production volume lags behind schedule. You need sales velocity to absorb this before variable costs, like 85% haulage, scale up.
Running Cost 5 : Structural Software
Software is Fixed Overhead
The $3,200 per month spent on structural design software is a fixed operational necessity for engineering capabilities. This cost must be covered monthly regardless of sales volume, as it enables the creation of the precise castellated beam geometry needed for fabrication.
Software Cost Breakdown
This monthly subscription pays for the specialized Computer-Aided Design (CAD) and structural analysis tools. These are non-negotiable inputs required before production starts. This $3,200 sits alongside facility rent and core payroll as critical pre-revenue spending.
- Covers engineering design licenses.
- Fixed monthly operational necessity.
- Essential for beam geometry creation.
Managing Design Spend
Since this is fixed, reducing it means negotiating longer contracts, perhaps for 24 months, to get a discount. You must track license use closely; paying for seats that aren't actively used by engineers hurts your burn rate. Don't defintely over-provision licenses early on.
- Negotiate annual vs. monthly rates.
- Audit license utilization quarterly.
- Avoid paying for idle seats.
Leveraging Fixed Costs
Every dollar spent on this $3,200 software subscription is spread across all beams you sell. Once you achieve volume, this fixed cost becomes a small percentage of your revenue, which is how specialized fabricators build strong gross margins.
Running Cost 6 : Heavy Haulage
Haulage Cost Shock
Heavy Haulage Logistics is a massive variable expense, hitting 85% of revenue by 2026. This cost structure defintely demands immediate focus on logistics efficiency before significant volume increases kick in. You can't scale volume if shipping eats the margin.
Cost Inputs
Haulage covers moving finished castellated beams to US construction sites. Estimating this requires knowing shipment weight, distance (zip code pairs), and carrier contract rates. Since it's 85% of revenue, even small rate changes drastically impact contribution margin.
- Beam dimensions and weight.
- Delivery zip codes.
- Carrier contract rates.
Cutting Shipping Bills
Since haulage is tied directly to sales, reducing it means negotiating better carrier contracts or changing delivery zones. Focus on optimizing truckload density, not just per-mile rates. If onboarding takes 14+ days, churn risk rises due to delivery delays.
- Negotiate volume discounts now.
- Maximize truck cube utilization.
- Use dedicated regional carriers.
Scaling Warning
The 85% haulage rate means your gross margin is razor thin until you secure better logistics contracts or shift production closer to major demand centers. This cost structure is unsustainable past early growth stages without intervention.
Running Cost 7 : Production Overhead
Overhead Monthly Hit
Production overhead, driven by utilities and tooling, hits about 23% of revenue. Based on Year 1 projections, this means roughly $19,000 in monthly costs before you even ship a beam. That's a fixed variable cost you must cover.
What This Covers
This overhead covers essential running costs tied directly to making steel beams. You need monthly revenue figures to calculate the exact spend, as it's 15% for Factory Utilities and 8% for Consumable Tooling. This $19,000 estimate anchors your variable cost structure early on.
- Utilities are 15% of sales.
- Tooling is 8% of sales.
- Total is 23% overhead.
Cutting Tooling Costs
Managing this means controlling energy use and tooling lifespan, since they scale with production volume. Focus on energy efficiency in the fabrication facility and negotiating bulk pricing on specialized cutting consumables. Avoid rush orders that spike utility usage unnecessarily.
- Audit utility consumption rates.
- Source tooling in bulk deals.
- Optimize cutting paths precisely.
Margin Impact
Because this 23% is variable, gross margin analysis must separate it from direct material costs. If your Year 1 revenue forecast changes by 10%, this overhead swings by $1,900 monthly, directly impacting contribution margin visibility.
