Raw materials for Construction

Rebar, cement, aggregates, glass, insulation and paint: reliable supply at project scale.

Sourcing for Construction starts with the right grade, consistent delivery and traceable documentation. Below you will find the material groups the sector uses, guide pages, current offers and verified suppliers.

How to source reliably

Work with verified (KYC) suppliers, request samples and a trial lot before large volumes, use independent inspection (SGS, Bureau Veritas, etc.) and tie payment terms to shipping milestones. The platform deal room keeps offer history, the digital contract and delivery steps on record in one place.

Material profiles

Polypropylene (PP): grades, MFI and sourcing guide

Polypropylene is one of the most widely used thermoplastics thanks to its low density, chemical resistance and easy processing. It is supplied as homopolymer, random and impact copolymer in injection, film, fibre and extrusion grades.

HDPE (high-density polyethylene) sourcing guide

HDPE offers a high strength-to-weight ratio, moisture barrier and chemical resistance, making it the choice for bottles, jerrycans, pipes and film. For pipe applications, the PE80/PE100 class and long-term pressure rating are decisive.

PVC resin: K-value, grades and sourcing

PVC resin is produced by suspension or emulsion polymerisation; the K-value indicates molecular weight and drives the application. Higher K-values suit flexible products, lower K-values rigid profiles and pipes.

PET chips (bottle & fibre grade) sourcing guide

The key parameter of PET chips is intrinsic viscosity (IV): bottle grade is typically 0.80–0.84 dl/g. Acetaldehyde level, colour (b*) and moisture directly affect quality in food-contact packaging.

Recycled plastics (rPET, rPE, rPP) sourcing guide

Recycled plastics are a fast-growing market for manufacturers aiming to cut carbon footprint and cost. Post-consumer (PCR) vs post-industrial (PIR) origin, contamination level, colour consistency and traceability certificates define quality.

Hot-rolled coil (HRC) buying guide

Hot-rolled coil is the base of flat steel products, used for pipes, sections, automotive chassis and general fabrication. Grade (S235–S355), thickness tolerance, edge condition (mill/trimmed) and surface (black/pickled) decide offer comparisons.

Rebar (reinforcing steel) buying guide

Rebar provides tensile strength in reinforced concrete. Yield strength, ductility class (B, C), weldability and the market standard (TS 708, BS 4449, ASTM A615) are the basis for comparing offers; request a mill test certificate (MTC) for every lot.

Stainless steel 304 vs 316: differences and sourcing

Austenitic grade 304 offers general-purpose corrosion resistance, while 316 with 2–3% molybdenum is far more resistant in chloride environments (seawater, chemicals). Surface finish (2B, BA, No.4), thickness and the nickel-linked alloy surcharge drive cost.

Aluminium ingot, sheet and extrusion sourcing guide

Aluminium is usually priced as LME plus a regional premium (e.g. Rotterdam duty-paid). For ingot, purity (P1020A 99.7%) matters; for flat and extruded products, alloy-temper (5083-H111, 6063-T5) and surface quality are key.

Copper cathode (Grade A) buying guide

Copper cathode to LME Grade A (99.99% Cu) is the main feedstock for wire, tube and alloy production. Fraud risk in this market is high: producer/brand verification, independent inspection, bank-backed payment (LC) and document checks are essential.

Titanium dioxide (TiO₂): rutile vs anatase sourcing guide

TiO₂ is the key white pigment providing whiteness and opacity in paints, plastics and paper. Rutile grades suit exterior and high-UV applications, anatase grades interior and paper uses; surface treatment, dispersibility and gloss are critical when comparing offers.

Natural rubber (TSR 20, RSS 3) sourcing guide

Natural rubber is mainly sourced from Thailand, Indonesia, Vietnam and Malaysia as technically specified blocks (TSR) or ribbed smoked sheets (RSS). Dirt, ash, volatile matter and Mooney viscosity define the grade; prices reference SGX/SICOM futures.

Portland cement and clinker sourcing guide

Cement type (CEM I, CEM II), strength class (42.5R, 52.5N) and conformity standard (EN 197-1, ASTM C150) must match the project specification. For bulk shipments port discharge capacity, and for bagged cargo palletising and moisture protection, drive cost and quality.

Wood pellets (ENplus A1) sourcing guide

ENplus A1 pellets are used for residential heating, I1–I3 industrial grades for boilers. Ash content, moisture, mechanical durability and calorific value are decisive; verifying the ENplus certificate number on the bag and in the official database protects against fraud.

Thermal coal sourcing guide (NAR/GAR, sulphur, ash)

Thermal coal calorific value is quoted on NAR (net) or GAR (gross) basis, and prices are usually indexed to API2, API4 or Newcastle. Total moisture, ash, sulphur, volatiles and size should be verified by independent sampling at load and discharge ports.

Glass fibre (roving, CSM, woven) sourcing guide

Glass fibre is the reinforcement of composites; E-glass is the most common type. Product form (roving, chopped strand mat, woven roving), tex, areal weight and resin-compatible sizing (polyester, vinyl ester, epoxy) drive selection. Boatbuilding may require class type approval.

Frequently asked questions

How do I find a reliable Construction supplier?

Prefer suppliers with the verified badge, a high trust score and completed deals. For large volumes, post a buying request to compare several offers and sign the contract in the deal room.

Can I buy small quantities as well?

Yes. For samples and small quantities you can message suppliers directly from the directory, free and commission-free. The deal room is designed for large, protected deals.
