ซื้อวัสดุก่อสร้างออนไลน์ ราคาถูกกว่าหน้าร้านจริงไหม

Not always. Items that are easy to ship, like paint and electrical or plumbing fittings, are often cheaper because the store has no showroom costs. But for heavy items like cement, bricks, sand and stone, delivery usually wipes out the difference and can make it cost more than a store near you. The right comparison is the total price delivered to your site, not just the unit price.

Three things. First, the TIS mark must be embossed on the steel itself, not just on a hanging tag. Second, the grade must match what your engineer specified — SD40 and SD30 are not interchangeable. Third, the weight per bar must meet the standard; bars lighter than standard were rolled thinner than they should be, and they're cheaper because there's less steel in them.

Type 1 Portland cement is for load-bearing structural work; blended cement is for bricklaying and plastering. They can't be swapped because their compressive strength is very different. On price, cement is heavy and expensive to ship — ordering in bulk from a store in the same province is usually better value than ordering from another province.

Take photos when the goods arrive, before you sign for them, then report it right away on the order page. The system records the time and photos so both sides can look back. If you can't agree, use the dispute center, where both buyer and store can submit evidence.

ราคาวัสดุแต่ละจังหวัดต่างกันมากไหม

Yes, and for some items by more than ten percent. Heavy items that are expensive to transport, like sand, stone and bricks, cost more the farther you are from where they're produced; items that ship easily vary less. The material prices page compares prices by province using Ministry of Commerce data.

ขอใบเสนอราคาจากหลายร้านพร้อมกันได้ไหม

Yes. Enter the items you need and send them as one request to several stores. Interested stores send their prices back, and the system lines them up item by item so you can see who offered what. If you already have a materials list (BOQ), create the request from it — no retyping.

ซื้อผ่านเว็บแล้วเอาไปลงบัญชีโครงการได้เลยไหม

Yes. When an order is linked to a project, it automatically appears as an expense in that project's accounts — no double entry — and the totals flow into the budget-vs-actual report.
