Granite Curbs from Granum Manufacturer

You can buy granite curbs at the manufacturer's price on our website. We offer all types of curb stones (or edging) from GP 1 to GP 5, which are used for forming and enhancing roads, sidewalks, garden paths, and public area platforms.

Standard Sizes of Granite Curbs

Granite curbs are classified according to GOST 32018-2012, where each type is designated by the abbreviation GP followed by a number from 1 to 5, determining the dimensions and scope of application. This approach allows precise selection of granite curbs based on load and aesthetic project requirements. For example, massive elements for highways differ from compact variants for pedestrian zones in height, width, and length, which affects the overall stability of the structure. Standardization simplifies design, eliminating errors in foundation calculations and compatibility with other paving materials.

GP1 Sizes: Large-Scale Solutions for Roads

The GP1 type is a granite curb with a length of 700–1200 mm, height of 300 mm, and width of 150–200 mm, designed to separate roadways from sidewalks on streets with heavy traffic. Its weight reaches 100–150 kg per linear meter, ensuring stability even under truck impacts. Installation of such granite products requires preliminary base preparation with crushed stone and sand to prevent subsidence over time. Without a proper foundation, even durable Ukrainian granite could shift under bus vibrations, compromising road integrity and creating hazardous situations at intersections.

GP2 and GP3: Balance of Strength and Aesthetics

For secondary roads and parking lots, GP2 is often chosen with parameters of 700–1000 mm in length, 250 mm in height, and 120–180 mm in width. This granite curb production variant is optimized for medium loads, where excessive massiveness is unnecessary, but durability is essential. GP3, in turn, has a length of up to 1500 mm and height of 400 mm, used at intersections to create smooth turns. Radius modifications of these types are produced in granite manufacturing via curved cutting, allowing rounded corners without joints and minimizing the risk of destruction from thermal expansions. Ignoring radius elements would cause straight granite curbs to lead to cracks in tiles at turns due to uneven pressure distribution.

Compact GP4 and GP5 for Gardens and Memorials

Smaller granite curbs GP4 (length 500–800 mm, height 150–200 mm, width 80–100 mm) are ideal for framing flower beds, park alleys, or grave sites. Their lightness simplifies manual installation, and the low profile does not visually dominate the landscape. GP5 is even more compact — up to 400 mm in length and 100 mm in height — used for miniature paths in private gardens. Buying granite of this size is cost-effective for small projects where every centimeter counts, and excessive height could disrupt harmony with plants or gravestones.

Custom Radius Curbs

In addition to standard ones, our granite manufacturing includes radius elements with curvature from 1 to 15 meters. They are created on CNC machines, where granite from the manufacturer is processed according to customer drawings. This is necessary for fountain complexes or oval squares, where straight granite curbs would result in unaesthetic corner joints. Without radius inserts, fountain water would erode the soil, and tiles would fan out, requiring annual backfilling and leveling.

How Much Does a Granite Curb Cost

The cost of a granite curb is formed by several factors, from the rock grade to the order volume. Pricing is per linear meter, simplifying budget planning for large projects. Unlike imported analogs, our granite from the manufacturer excludes customs markups, making the granite curb price competitive with identical quality. For an accurate calculation, leave a request — a specialist will consider all project nuances.

Factors Influencing the Price

The granite grade determines the base cost: Kapustiansky with red inclusions is more expensive than Pokostovsky gray due to rarity and decorativeness. Next is the size — larger dimensions increase the price due to higher material consumption in granite production. Surface treatment adds costs: polishing requires additional grinding hours, while sawn variants are cheaper. For wholesale over 500 linear meters, a flexible discount system applies, plus samples of rock types can be sent for selection.

What Is Included in Delivery Cost

Transportation of granite products is carried out by flatbed trucks with crane manipulators capable of unloading up to 20 tons per trip. The price includes loading at the warehouse, but unloading at the site is paid separately if no own equipment is available. For regions outside Ukraine, we organize export with origin certificates. To avoid delays, coordinate the supply schedule in advance considering the season — winter roads may be complicated by snow.

Comparison with Alternatives

Concrete curbs are cheaper initially but require replacement after 5–7 years due to chipping. Granite stone lasts 50+ years without losing properties, recouping the difference through no repairs. Savings also show in aesthetics: granite products do not fade under UV rays, retaining their original appearance, while painted concrete dulls and needs coating renewal.

Advantages of Granite Curbs in Modern Landscaping

Urban infrastructure faces constant challenges from weather, traffic, and vandalism, so materials must combine strength with visual harmony. Granite curbs solve this by creating clear boundaries between functional zones. Their installation prevents gravel from spreading onto lawns, maintaining tidiness year-round, and directs water flow into storm drains, minimizing flooding.

Durability in Extreme Conditions

Ukrainian granite withstands up to 300 freeze-thaw cycles without cracks due to a density of 2.6–2.7 g/cm³. In coastal cities, road salt reagents cause no corrosion, unlike concrete. Neglecting granite curbs would cause asphalt to crumble at edges within a year, requiring patch repairs and increasing road maintenance costs.

Environmental Safety

Natural stone emits no toxins when heated, important for playgrounds. In granite production, we use only mechanical processing without chemicals, preserving material purity. The radiation background of Korostyshiv rocks is 3–5 times below the norm, confirmed by certificates. This makes granite products safe even for areas with high sanitary requirements, such as hospital courtyards.

Installation and Maintenance

Laying requires a 20–30 cm deep trench with a sand-cement cushion. Joints are filled with mortar for monolithicity. Maintenance is minimal — periodic washing from dust suffices. Without regular cleaning, moss may accumulate on rough surfaces, but this is resolved with a pressure water jet. Unlike plastic analogs, granite does not deform from heat or crack from frost.

Curbs by Type of Processing

Surface processing determines not only appearance but also the friction coefficient, affecting safety. Each method has its technology and application area in natural stone product manufacturing, selected based on climate and usage intensity.

Polished Granite Curb

Grinding to a mirror shine reveals color depth and texture. Used in premium projects: shopping mall entrances, memorials. Drawback — slipperiness in wet weather, so combined with anti-slip inserts or limited to dry zones.

Sawn Surface

Standard matte cut with a diamond disc. Universal for most sites. Requires no additional processing time, simplifying granite curb production and speeding up delivery.

Thermal Treatment for Safety

Gas burner burns off the top layer, creating relief. Friction coefficient 0.6–0.8. Ideal for ramps, stairs, and areas near water bodies with constant humidity.

Chipped Variant with Stylization

Hydraulic splitter forms irregularities, imitating manual hewing. Applied in historical reconstructions, eco-parks, and country estates where an antique effect is needed without losing strength.

How to Buy or Order a Granite Curb

The process starts with selection from the catalog on the website. Then, consultation with a specialist who will consider loads, climate, and budget. We draw up a contract, organize production and delivery to any city in Ukraine.
