In the increasingly competitive sheet metal fabrication industry, the core challenge for management is not 'can we get orders,' but 'can we make money on the orders we get.' Return on Equity (ROE) is the ultimate metric for measuring shareholder returns, directly determining whether a company has the capacity for sustained financing, expansion, and dividends.

However, sheet metal companies generally have low ROE — industry average is only 8%–15%, far below high-margin industries like baijiu (30%+). This is not an unchangeable fate. This article uses the Dupont analysis framework to systematically outline viable paths for sheet metal companies to improve ROE from three dimensions: net profit margin, asset turnover, and equity multiplier.

Core Thesis: The key to improving ROE for sheet metal companies is not 'borrow more money,' but 'fully utilize equipment, reduce waste, and collect receivables on time.'

I. What Is ROE? Why Should Sheet Metal Companies Care?

ROE (Return on Equity) = Net Income / Equity. It measures how much profit a company generates per yuan of shareholder capital invested.

For sheet metal companies, ROE matters at three levels:

• Financing capacity: Higher ROE means banks and investors are more willing to extend credit; companies with ROE below 8% long-term often face difficulty and high costs in financing.

• Competitive signal: Among peers, companies with consistently leading ROE have more leverage in customer negotiations and supplier bargaining.

• Value creation: ROE > cost of capital (WACC) means genuinely creating shareholder value; otherwise, the bigger the company grows, the poorer the shareholders become.

Structural reasons for low ROE in the sheet metal industry:

• Raw materials (steel/aluminum sheets) account for 50%–60% of total cost, setting a low ceiling on gross margin;

• Heavy equipment assets — laser cutters, bending machines, and automated production lines cost millions;

• Highly fragmented industry, fierce price competition, strong customer bargaining power.

But all three problems can be partially addressed through systematic management — and Dupont analysis provides exactly this systematic lens.

II. The Dupont Analysis Framework: Breaking Down ROE

2.1 The Dupont Formula

Dupont analysis breaks ROE into the product of three drivers:

ROE = Net Profit Margin × Asset Turnover × Equity Multiplier

Where:

• Net Profit Margin = Net Income / Revenue (measures profitability)

• Asset Turnover = Revenue / Total Assets (measures asset utilization efficiency)

• Equity Multiplier = Total Assets / Equity (measures leverage)

The product of these three factors equals ROE, representing three entirely different improvement paths.

2.2 Comparing Dupont Profiles Across Industries

The table below shows how similar ROE levels can be driven by radically different structures:

Key Insight: Similar ROE, but entirely different drivers. Moutai relies on extremely high profit margins, Walmart on extremely high turnover, banks on extremely high leverage. Sheet metal companies need to find their own breakthrough path.

2.3 Typical Dupont Profile for Sheet Metal Companies

Current industry averages (reference values):

• Net profit margin: 4%–8% (medium-low, suppressed by material costs and price competition)

• Asset turnover: 0.8–1.2 (medium — equipment utilization is the key driver)

• Equity multiplier: 1.5–2.5 (medium leverage — banks are conservative with manufacturing credit)

• Combined ROE: approximately 8%–15%

Improvement targets (after 1–2 years of systematic improvement):

• Net profit margin: 6% → 8% (product mix optimization + scrap reduction)

• Asset turnover: 1.0 → 1.25 (improve OEE + compress receivables)

• Equity multiplier: 1.8 → 2.0 (moderate introduction of factoring financing)

• Improved ROE = 8% × 1.25 × 2.0 = 20%, nearly doubling — fully achievable

III. Path One: Improving Net Profit Margin

Net profit margin is the most direct reflection of a company's core competitiveness among the three drivers. For sheet metal companies, the core logic for improving net profit margin is: through product mix upgrades and refined cost management, leave more profit on every order.

3.1 Get Profit from Product Mix — Raise Prices

Exit low value-added segments; enter high value-added tracks

Gross margin varies dramatically across sheet metal product types:

• Simple stampings, outsourced bending parts: gross margin typically only 10%–15%, with transparent pricing and severe homogeneous competition;

• Precision structural parts + integrated surface treatment: gross margin can reach 25%–35%, with high customer loyalty;

• New energy track (EV charger enclosures, energy storage cabinets, solar mounts): customers have high quality requirements and low price sensitivity, gross margin can reach 20%–30%.

Recommended actions:

• Review current product mix; for products with gross margin below 15%, high customer concentration, and no strategic value, formulate a gradual exit plan;

• Prioritize developing "sheet metal + coating/powder coating" one-stop delivery — integrated service offerings command 20%–30% premium over pure processing;

• Establish annual framework agreements with new energy, medical device, and industrial automation customers to lock in high-margin stable orders.

Differentiated pricing: different price strategies for different customers

• Strategic key accounts (annual orders > RMB 2M): offer price discounts in exchange for long-term orders and priority payment;

• Regular customers: maintain standard pricing, no arbitrary discounts;

• Small spot orders (single order < RMB 10K): charge premium pricing or set minimum order quantities to reduce management cost dilution.

3.2 Get Profit from Cost Structure — Reduce Costs

Raw material costs (50%–60% of total cost)

• Centralized procurement: sign annual agreements with fixed suppliers for bulk negotiation, reducing purchase price by 3%–5%;

• Optimize nesting: introduce nesting software (e.g., SigmaNEST) to raise sheet utilization from 75% to 85%, reducing material waste;

• Refine safety stock: procure-to-order to avoid raw material backlog tying up working capital.

Labor costs (15%–25% of total cost)

• Automate key processes: laser cutting auto-loading/unloading, bending robots — one robot can replace 2–3 workers, payback within two years;

• Multi-process composite workers: upgrade operators from "single process" to "cutting + bending + inspection" composite roles, reducing wait time and transfer losses;

• Performance system: implement piecework + quality bonus structure, incorporating rework rate into performance evaluation to reduce hidden rework costs.

Reduce scrap rate and rework costs

• A 1 percentage point reduction in scrap rate saves a company with monthly revenue of RMB 5M approximately RMB 100K–200K per year;

• Establish first-piece inspection and patrol inspection systems — catch problems at the cutting stage rather than after assembly rework;

• Build equipment logs for molds and cutting tools, refine management of replacement cycles, avoid excessive wear causing scrap.

IV. Path Two: Improving Asset Turnover

Asset turnover is the largest room for improvement in sheet metal companies and the factor most directly affecting profitability. Core logic: the same assets, generating more revenue.

4.1 Improve Equipment Utilization — Fixed Asset Turnover

Understanding OEE (Overall Equipment Effectiveness)

OEE = Availability × Performance Efficiency × Quality Rate

• Industry average OEE is approximately 55%–65%; excellent companies can reach 80%+;

• Every 10 percentage point improvement in OEE is equivalent to gaining free capacity from an additional machine;

• In reality, most sheet metal companies' OEE losses mainly come from: excessive changeover time (can be 15%–20% of shift production time), equipment failure waiting, and quality rework.

Specific measures to improve OEE

• Implement SMED (Single-Minute Exchange of Die): compress changeover time from 60 minutes to under 20 minutes;

• Run laser cutters on three-shift 24-hour schedules, eliminate nighttime downtime;

• Establish preventive maintenance plans to reduce unplanned downtime;

• Introduce MES system to real-time monitor each machine's utilization — respond immediately to bottlenecks;

• During equipment idle periods, proactively take outsourced processing to convert fixed costs into extra revenue.

4.2 Compress Working Capital — Current Asset Turnover

Accounts receivable management

Receivables turnover days are a silent killer of manufacturing ROE. Current industry status: approximately 45–90 days, target: compress to 30–45 days.

• Promote bill settlement: require customers to pay with bank acceptance bills — upon maturity, can be discounted, actually shortening payment terms by 30–60 days;

• Introduce factoring financing: package core customer receivables and sell to factoring companies for early collection, annual cost 3%–5%, but releases working capital;

• Set collection KPIs: link sales commissions to receivables recovery; suspend taking orders on receivables overdue beyond 60 days;

• Leverage supply chain finance platforms (e.g., core enterprise reverse factoring): rely on major customer credit to obtain receivables funding at low interest rates.

Inventory management

• Raw materials: procure-to-order, establish safety stock models to reduce dead stock tying up capital;

• Work-in-progress: implement pull production (JIT) to reduce semi-finished goods accumulation;

• Finished goods: arrange shipping immediately upon completion — avoid warehouse retention beyond 3 days;

• Regular inventory counts: quarterly clearance of slow-moving inventory; promptly dispose of dead stock to release capital.

Prepaid expenses and fixed assets

• Establish supplier credit ratings — for high-quality suppliers, reduce prepaid ratios and shift to payment upon delivery inspection;

• Negotiate monthly settlement payment terms with major raw material suppliers;

• Prioritize operating leasing over outright purchase for non-core equipment, preserving cash to improve capital efficiency.

4.3 Advance Asset-Light Transformation

• Do not build in-house surface treatment processes (powder coating, electroplating); source professional outsourcing to reduce fixed asset investment;

• Prioritize leasing over purchasing facilities, especially during business expansion;

• Outsource non-core auxiliary processes (logistics, packaging); focus on core cutting, bending, and welding capabilities.

V. Path Three: Moderate Optimization of Equity Multiplier

Equity multiplier (leverage) is an amplifier for ROE, but also an amplifier for risk. With high cash flow volatility in sheet metal companies, equity multiplier is recommended to be controlled within 2.5×. The core principle for leveraging: replace high-cost capital with low-cost capital; use structural instruments to replace pure loans.

5.1 Financing Instruments Suitable for Sheet Metal Companies

5.2 Red Lines for Leverage Usage

• Be vigilant when equity multiplier exceeds 3×: during off-seasons or raw material price fluctuations, excessive leverage can easily cause cash flow strain;

• Annual interest expense on interest-bearing debt should not exceed 40% of EBIT (Earnings Before Interest and Taxes);

• Prioritize supply chain finance instruments (low cost, no collateral), second choice bank loans, use private financing with caution.

Important Note: Using supply chain finance instruments (factoring/reverse factoring) to improve equity multiplier is the optimal path for sheet metal companies — both amplifying ROE and improving cash flow, with costs typically 1–2 percentage points lower than bank loans.

VI. Action Priority Matrix

Organize the above improvement measures by "speed of impact" and "magnitude of improvement":

6.1 Setting Quantitative Improvement Targets

Recommend the following as annual KPIs:

• Equipment OEE: 60% → 75% (improve by 15 percentage points)

• Receivables turnover days: 75 days → 45 days (shorten by 30 days)

• Scrap rate: 3% → 1.5% (reduce by half)

• Raw material utilization: 76% → 84% (improve by 8 percentage points)

• Annual net profit margin: 6% → 8% (improve by 2 percentage points)

If all five KPIs above are achieved simultaneously, combined ROE can rise from 11% to 18%–20%, reaching industry-leading levels within 3 years.

VII. Conclusion: ROE Is a Comprehensive Health Check of Management Quality

Dupont analysis is not merely a financial tool — it is fundamentally a health check of management capability — net profit margin tests product strategy and cost management, asset turnover tests operational efficiency and capital management, and equity multiplier tests financing structure and risk management.

For sheet metal company management, there is no shortcut to improving ROE, but there is a system. Starting today, it is recommended to review changes in the three Dupont factors quarterly:

• Is net profit margin rising or falling? Is it due to product mix changes or cost overruns?

• Is asset turnover improving? Is it driven by equipment utilization gains or receivables dragging?

• Is equity multiplier within a reasonable range? Are financing costs within the affordable boundary of profitability?

Linking the three financial statements and reviewing the three metrics together is what truly builds enterprise management on a data-driven foundation, rather than making decisions by gut feeling.

Ultimate Goal: Raise sheet metal company ROE from the industry average of 10%–12% steadily to a premium level of 20%, truly becoming a company that creates value for shareholders.
