1. Scope and Applicability

This candidate covers factory-gate iron/steel sheet piling, including hot-rolled and cold-formed interlocking piles and factory-drilled, punched or assembled variants, and welded built-up angles, shapes and sections. Product shape and function determine sheet-pile inclusion: cold forming does not turn a sheet pile into a generic cold-worked section. The two product families share traced steel feed, accepted net mass, finishing and loss accounting; their forming and joining burdens remain route-specific.

Exclude installed retaining walls/cofferdams, piling/extraction service, project design, use and end of life; unwelded ordinary hot/cold-worked sections, hollow sections, pipes, rails and unrelated fabricated structures need their own methodology. Admit iron/non-alloy, alloy and stainless grades only as explicitly declared grade/chemistry/delivery states with actual supplier feed, qualified welding procedure and conditional heat/surface processing. No generic route, acid recipe or corrosion performance transfers across grades. No retaining capacity, design life, fixed composition or industry yield is asserted.

Field	Value
What	Sheet piling of iron or steel and welded angles, shapes and sections of iron or steel
How much	1 kg
How well	product family and interlock/section geometry; hot-rolled or cold-formed sheet-pile route; welded built-up section route; specification and edition; grade and heat chemistry; thickness and length; delivered net unit mass; weld procedure, filler and shielding system; acceptance tests; coating system and coating mass; supplier feed form and completed upstream operations; site, period, electricity interface and geography
How long or cycle	One accepted supply at manufacturing gate; no installed functional lifetime
reference_flow_link	`final_product`

Field	Value
Reference amount	1
Reference product flow	Sheet piling of iron or steel and welded angles, shapes and sections of iron or steel
Reference flow property	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`
Reference unit group	Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66`
Reference unit	kg
Required qualifiers	product family and interlock/section geometry; hot-rolled or cold-formed sheet-pile route; welded built-up section route; specification and edition; grade and heat chemistry; thickness and length; delivered net unit mass; weld procedure, filler and shielding system; acceptance tests; coating system and coating mass; supplier feed form and completed upstream operations; site, period, electricity interface and geography

Declare every qualifier in dataset metadata. For a nonwelded pile, declare weld procedure, filler and shielding system as not_applicable with route evidence. For a bare product, declare coating/sealant formulation as not_applicable and retained coating/sealant mass as zero with acceptance records; an unknown surface state is not bare. D is positive accepted net product mass over the matched reporting period, including retained weld metal and only the contractual coating/sealant supplied at that gate. Keep steel-body, coating and sealant masses separate; exclude packing, rejects and free water. A structural design comparison requires a separate functional study.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	final_product	Mass	kg	cp_final_product measures D; each attributable period exchange is divided by D.
conversion	all exchanges	Row-specific property	kg; m3; kWh; MJ	Retain raw units and conversion evidence; 1 kWh = 3.6 MJ. Gas volume requires temperature/pressure, purity and density or NCV; wet residue requires moisture and element assays.
balances	steel, weld, coating, water and chemicals	Mass	kg	Never sum gross steel kg with contained-Fe kg. For each actual element e, measured gross mass times its own same-element assay defines every feed, weld, steel body, scrap, scale, slag, sludge, effluent, release and opening/closing stock term. Include nonsteel contributions where present; close each element separately. Carbon/alloy-element oxidation, oxygen uptake and water/chemical reactions require separate measured reaction balances; no pure-iron or fixed-alloy conversion. Cancel internal rework but retain repeated energy and consumables.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Received steel beam blank/bloom/billet, hot-rolled coil, plate or individual profile; declare supplier-completed operations, temperature and coating
starting_condition_role	Supplier intermediate product
product_classification_scope	Sheet piling of iron or steel and welded angles, shapes and sections of iron or steel
recursive_input_rule	Purchased sheet pile or welded section retains distinct supplier burden; internal transfers cancel, never become new production or recycling credits
upstream_dataset_requirement	Qualified steelmaking/casting/rolling by actual feed route, grade, supplier and geography; utilities, chemicals, transport and waste destinations; missing links are explicit gaps, never zero
disclosure	product family and interlock/section geometry; hot-rolled or cold-formed sheet-pile route; welded built-up section route; specification and edition; grade and heat chemistry; thickness and length; delivered net unit mass; weld procedure, filler and shielding system; acceptance tests; coating system and coating mass; supplier feed form and completed upstream operations; site, period, electricity interface and geography

boundary_surface	surface_gate	Include contract surface operations and outsourced work before gate, with separate chemicals, energy, retained coating and wastes; later installation/field application is excluded.	`epa-fabricated-metal-2021`
boundary_completeness	all exchanges	Audit the site: add each actual fuel, shielding mixture, chemical, transport service, packing material, waste and emission as its own atomic exchange. Record and justify capital/infrastructure treatment. Candidate cards are conditional, unknown is not absent.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_hierarchy	shared processes	First isolate product and route by batch metering/subdivision; where unavoidable allocate by demonstrated physical causation (machine time, weld work, heated load or treated area). Explain other relationships with sensitivity; mass alone is not automatically appropriate across different routes.	`ec-pef-2021`
scrap_and_rework	metal residues	Keep rejects, internal rework, external scrap and actual saleable co-products distinct. Retain waste treatment/transport; no automatic avoided-steel credit inside this foreground package. Declare recycling method and end-of-waste boundary separately for any full LCA.	`ec-pef-2021`

Structured rule index

This index comes from verified structured.yaml and retains the canonical English rule text.

System boundary rules · 3

Rule ID	Applies to	Rule	Source IDs
`boundary_route`	all processes	Include the actual selected route, preparation, joining, finishing, inspection, attributable handling and controls through the gate; distinguish upstream coil hot rolling from local cold forming.	ec-fmp-bref-2022, arcelormittal-cold-piles-2025
`boundary_surface`	surface_gate	Include contract surface operations and outsourced work before gate, with separate chemicals, energy, retained coating and wastes; later installation/field application is excluded.	epa-fabricated-metal-2021
`boundary_completeness`	all exchanges	Audit the site: add each actual fuel, shielding mixture, chemical, transport service, packing material, waste and emission as its own atomic exchange. Record and justify capital/infrastructure treatment. Candidate cards are conditional, unknown is not absent.

Allocation rules · 2

Rule ID	Applies to	Rule	Source IDs
`allocation_hierarchy`	shared processes	First isolate product and route by batch metering/subdivision; where unavoidable allocate by demonstrated physical causation (machine time, weld work, heated load or treated area). Explain other relationships with sensitivity; mass alone is not automatically appropriate across different routes.	ec-pef-2021
`scrap_and_rework`	metal residues	Keep rejects, internal rework, external scrap and actual saleable co-products distinct. Retain waste treatment/transport; no automatic avoided-steel credit inside this foreground package. Declare recycling method and end-of-waste boundary separately for any full LCA.	ec-pef-2021

Validation rules · 4

Rule ID	Applies to	Rule
`validate_reference`	final_product	Require D > 0, finite kg and every qualifier; distinguish accepted steel body, weld metal, coating/sealant and packing.
`validate_route`	all processes	Verify hot/cold sheet-pile and welded-section modules against records; bypass only completed supplier operations with burden links. Reject installed-service or unqualified-grade substitutions.
`validate_balance`	all exchanges	Check gross mass and every measured same-element balance separately, water/chemical/weld-flux/coating closure, stock matching, internal transfers and rework energy; investigate residuals beyond measured uncertainty. Never enforce pure Fe or fixed alloy fractions.
`validate_exchange`	inventory	Require atomic exchanges, dimensionally supported units, matched reporting period and explicit supplier/treatment links; keep missing UUIDs or quantities unresolved, not zero or guessed.

Processes and inputs/outputs · 8

Process ID	Process name	Input flows	Output flows
`receipt`	Steel receipt and route preparation	5	0
`hot_pile`	Hot rolling of sheet piling	3	4
`cold_pile`	Cold forming of sheet piling	2	1
