General Construction Casting

General Construction Casting

General construction casting is the production of metal products and elements widely used in civil and industrial construction, as well as in urban landscaping. Main purpose:

• Utility infrastructure: Manhole covers, storm drain grates, drainage channels, water drainage systems.
• Landscaping elements: Light poles, park benches, litter bins, decorative fencing, tree grates.
• Architectural and decorative elements: Balustrades, columns, decorative friezes, brackets, stair railings, finials.
• Functional parts: Counterweights, embedded parts, fixing elements, special supports. Key technical characteristics:
• Material: Most commonly iron (gray, ductile, malleable), steel (carbon, stainless), aluminum alloys, bronze, and brass for decorative items.
• Casting method: The most common are sand casting (for large, less complex items), investment (lost foam) casting (for high precision and complex shapes), chill casting (for series production and good surface quality).
• Size and shape: From small decorative elements to large manhole covers, supports, and architectural fragments. Items of any complexity can be produced.
• Surface quality: Ranges from functional, anti-slip (for manhole covers) to smooth, paint-ready, or highly decorative with fine detail for decor elements.
• Strength and durability: High resistance to mechanical loads, abrasion, corrosion, and environmental exposure.
• Weather resistance: Products are designed for long-term outdoor use, withstanding temperature swings, precipitation, UV exposure, and chemical agents. Production capabilities: Type of production: Modern Technologies mini-plant Casting method:
• Lost foam casting (LFC) - saves on molding, delivers high casting accuracy, minimizes machining allowance, and gives excellent surface finish. Ideal for complex shapes.
• V-process (vacuum sealed molding) - a modern, cost-effective, and environmentally friendly technology that produces high-accuracy castings with minimal defects and reduces consumption of molding materials. Floor area: From 250 m² Output: From 800 tonnes of finished products a year. Wholesale price in Kazakhstan - from $0.9/kg and up Margin - 30⁠-⁠65% (depends on material, complexity, order volume, and finishing). Kazakhstan market price (approximate benchmarks): By kilogram:
• Cast-iron manhole covers and storm drains (uncoated): from $0.9/kg to $1.8/kg.
• Decorative cast iron (painted): from $1.6/kg to $4/kg.
• Aluminum elements: from $5/kg to $10/kg (depends on alloy and complexity).
• Bronze/brass elements: from $8/kg (for simple items) to $20+/kg (for complex decorative items). By unit price (finished products, examples):
• Cast-iron manhole cover, “Heavy” type (GOST): from $30/pc to $70/pc.
• Cast-iron storm drain (small): from $16/pc to $30/pc.
• Cast-iron park bench (one side panel): from $50/pc to $120/pc.
• Decorative fencing element (iron): from $20/pc to $100/pc (depending on size). Price depends heavily on the material grade, manufacturing complexity, dimensions, weight of the item, batch size, and required finishing (machining, painting, patination).
